Apple is planning job memory

6 October 2011 09: 53 GMT state Steve Wozniak founded Apple with Steve Jobs Apple said that "a firm which was planned after his death Steve's extraordinary life on Wednesday".

In an internal memo to staff said Apple CEO Tim Cook, who closely with jobs "a dear friend and an inspiring mentor had lost".

"We will honor his memory by dedicate ourselves to continuing the work that he loved so much", he said.

Meanwhile, Apple co-founder Steve Wozniak said, on that his friend would live on its products.

"We have something that we don't again get lost, but how I see it, though, as people love products, that he so much in the development of the means, which he brought much life in the world," he said in an interview with PA.

Wozniak, said that he had seen last time of jobs three months ago, shortly after his temporary medical leave Apple to unveil iCloud service.

Apple Orchard

Wozniak said that Apple market-changing products, from the Macintosh computers with the iPod, iPhone and iPad - were wanted on jobs instinctive feel for what from technology.

"While all other fumbling was to try to find the formula, he had the better instincts."

The two met at high school and reconnected, deleted after jobs out of school and returned to California.

Together she attended meetings of the Homebrew Computer Club - a group of computer hobbyists.

Mr. jobs saw potential in the home-made machine Wozniak, and she began garage Apple Computer Inc. in jobs parents in 1976.

Wozniak came up with the name after seeing an Apple Orchard jobs.

Unfortunately missed

Tributes to the former head of Apple continue pouring on Twitter.

Mac fans who tweeted Stephen Fry: "Woke to the news of Steve Jobs death." He has changed the world. I was a little known and admired him completely. "Love for Apple and his family."

In the meantime, Amstrad said founder Mr Zucker "" gutted ";" Steve Jobs died. We began our computer-biz at the same time and was until the 1980s. Great visionary. Unfortunately missed. "RIP".

BBC Director General Mark Thompson paid tribute to Mr jobs at the beginning of a meeting in the internal staff for the proposed cuts in the Corporation layout.

"It's hard to keep someone that media has changed in the last 10 years."Our condolences to his family, Mr Thompson said.

Samsung, Micron Back New Memory Type to Challenge DDR3

AppId is over the quota
AppId is over the quota

Samsung Electronics and Micron Technology on Thursday announced the creation of a consortium around a new low-power memory called Hybrid Memory Cube, which could challenge DDR3 memory in high-performance computers in a few years.

The Hybrid Memory Cube Consortium will bring together device makers and chip companies to develop an open specification around the new memory type, the companies said in a joint statement.

Hybrid Memory Cube (HMC) promises to surpass current memory technologies such as DDR3 DRAM on performance and power consumption, the companies said. The memory is initially targeted for use in markets such as networking, high-performance computing and energy, said Scott Graham, general manager of the DRAM solutions group at Micron.

Graham couldn't pin a specific date on when the memory will reach the market. But the initial specifications will be released next year, and Graham estimated mass production of the memory to begin in 2015.

HMC will deliver memory bandwidth that could speed up network performance, and pipes to drive up CPU performance in high-performance computers, according to the consortium's website. Other consortium members include Altera and Xilinx, which are known for integrated chips and FPGAs (field-programmable gate arrays) used in the high-performance computing market.

The HMC memory type was demonstrated last month by Intel working an experimental CPU to run a solar-powered computer. Intel said that HMC was seven times more power-efficient than current DDR3 memory.

The consortium on its site said "a single HMC can provide more than 15 [times] the performance of a DDR3 module." A "cube" also utilizes 70 percent less energy per bit than DDR3 memory, it said.

PCs are not one of the primary target markets for HMC, though it is hard to predict how the memory will be used in the future, Graham said. Intel and other CPU makers are not members yet, though they have been invited to join the consortium. Intel and Micron currently are in a joint venture called IM Flash Technologies to make flash memory.

DDR4 is expected to succeed current DDR3 memory, which is now going into most new computers. Analysts have said DDR4 could reach PCs and servers by 2014 or 2015.

HMC was developed by Micron in close partnership with Intel, said Mike Howard, principal analyst of DRAM and memory at IHS iSuppli. As one of the world's largest memory makers, Samsung is a crucial partner to Micron and could help drive adoption, Howard said.

The technology involves an advanced memory controller and chips connected through an emerging silicon stacking technology called Through Silicon Via. The real promise of HMC is for server customers, and one memory cube could potentially replace 10 DDR3 DIMMs in a server.

"It really makes the memory operate faster and smarter," Howard said.

Considering the initial price, it's unlikely to go into consumer products anytime soon, Howard said. However as adoption grows and costs come down, HMC could be used in PCs, tablets and smartphones, but that could be many years out, Howard said.

TECHNOLOGY, Percona Curbs MySQL Memory Hunger

Percona has updated its version of MySQL so that the software's storage engine consumes less working memory, potentially increasing its suitability for tasks requiring an in-memory database, the company announced Friday.
The in-memory storage engine of Percona Server 5.5.15 now can hold all MySQL data types, including the previously unsupported BLOB and TEXT data types, which could also broaden its appeal to large-scale Web services companies.
If a deployment "has very small memory tables, [this version] may save a few megabytes of memory. It's no big deal. But if you are using tens or hundreds of gigabytes of data in memory, that is where you will find that our changes have an advantage," said Percona founder and CEO Peter Zaitsev.
Founded in 2006, Percona bills itself as the largest and oldest independent MySQL services vendor outside of Oracle. Internet-facing companies such as GroupOn, RightNow, Answer.Com, 37Signals and the British Broadcasting Corporation have availed themselves of Percona's services. Percona Server is an open source version of MySQL with a number of enhancements for production use. Percona sells support for the server.
For this release, the company modified the MySQL MEMORY storage engine, which was designed to store database tables in a server's working memory, eliminating the need to write each change to a disk, which can slow transaction speeds. For jobs such as hosting a website, MySQL Memory can significantly speed response times.
A number of limitations have hobbled the basic version of MySQL MEMORY, Zaitsev said. Most notably, MEMORY (formerly known as HEAP) can work only with a subset of data types allowable in MySQL, notably only those with fixed lengths.
With fixed-length data types, each entry to the database will be stored in an identically sized storage block. Because most entries won't use all the space in their storage blocks, this approach is inherently inefficient, due to all empty space it creates. "For many problems, you have to store strings of different lengths," Zaitsev said.
On disk drives, where space is relatively cheap, this waste is not a huge deal. On the more expensive RAM, however, such waste is costly.
Percona Server 5.5.15, which is based on MySQL 5.5.15, comes with an enhanced version of MySQL MEMORY that can work with any MySQL data type, including variable-length data types such as BLOB and TEXT.
EBay principal developer Igor Chernyshev first developed this technology in 2008, in order to improve memory usage for that company's services. His version allowed entries encoded in the VARCHAR data type to be stored at their natural lengths, rather than at a larger fixed length. Percona then added support for the TEXT and BLOB data types, both of which can be used to store large strings of text.
How much memory this version will save will vary greatly from one implementation to another, Zaitsev said. It could cut as much memory requirements by as much half or even more, on the data types formerly used. It also opens the use of in-memory databases to organizations that only use variable-length data types before, and were not willing to convert the data to a fixed-length data type.
In-memory databases are growing increasingly popular as more organizations set up Web-facing or real-time systems, which need to be as responsive as possible. Oracle's TimesTen, SAP's HANA database and VoltDB all serve this market as well.

TECHNOLOGY, Tablets, Smartphones to Get Speed Boost With New Memory

A new form of mobile DDR3 memory that can speed up tablets, smartphones and laptops could appear in devices starting as early as late next year, with adoption ramping up in 2013, analysts said on Thursday.
Low-power DDR3 memory -- also called LPDDR3 -- will bring a bigger data transfer pipe to tablets and smartphones, which could translate into better performance and longer battery life, analysts said. Standards-setting organization JEDEC (Joint Electron Device Engineering Council) is defining the specifications for LPDDR3, which draws heavily from conventional DDR3 DRAM found in PCs today.
The mobile memory will replace LPDDR2, which is found in current smartphones and tablets like Apple's iPad. Memory maker Samsung Electronics this week said it had developed a 4GB LPDDR3 DRAM unit, which it called the industry's first. The mobile memory can transfer data at up to 1,600 megabits per second, which is 1.5 times faster than LPDDR2, while consuming 20 percent less power.
Tablets and smartphones will need to switch to a faster form of memory as devices and applications become more resource intensive, said Mike Howard, principal analyst for DRAM and memory at IHS iSuppli.
"As far as viewing and recording high-definition content, it's going to be a better experience with LPDDR3 because of the bandwidth available," Howard said.
Mobile memory is key in bringing more multitasking to devices, Howard said. As hardware advances to include faster processors and higher resolution screens, LPDDR3 will keep the ball rolling on switching between videos, phone calls and other applications, Howard said.
In addition to better performance, LPDDR3 memory is designed to consume less power than its predecessor, said Dean McCarron, principal analyst at Mercury Research. A combination of low-power consumption and more bandwidth could prolong battery life on tablets and smartphones, McCarron said.
"It is allowing lower power consumption that has an immediate benefit everywhere," McCarron said.
The memory type will initially be found in tablets and high-end smartphones, where performance matters more, McCarron said. But as is the case with most new technologies, LPDDR3 initially won't be cheap, but as production ramps, LPDDR2 will be phased out and its successor will appear in more devices. As adoption increases, prices will fall and that will be reflected in the prices of smartphones and tablets.
"Eventually all these technologies become a commodity," McCarron said.
Intel has also been pushing the use of low-power memory in ultrabooks, which is being promoted by the chip maker as a category of thin-and-light laptops with tablet-like features. Analysts said that there are still a lot of unknowns about components that may be used in ultrabooks, but LPDDR3 may be in those PCs in coming years. LPDDR3 offers close to a 15 percent power reduction compared to standard DDR3, according to JEDEC.
JEDEC is still developing LPDDR3 specifications, but that could be finalized soon, Howard said. Backing of the mobile memory could ramp once the specification is finalized. The world's top DRAM makers include Samsung, Hynix Semiconductor, Elpida Memory, Micron and Nanya, all of which are members of JEDEC.
JEDEC did not immediately respond to requests for comment on when it would finalize LPDDR3, but analysts estimated that it could be finalized by the end of the year.
In prior renditions of synchronous DRAM such as SDRAM, DDR and DDR2, JEDEC pushed hard on speed without worrying too much about power, said Jim Handy, director of Objective Analysis. With DDR3 and LPDDR3, JEDEC worked to bring the power specifications back down while continuing to increase speed.
But adoption typically depends on other parts of the system, Handy said. For cell phones it's less sudden than it is in PCs, where a single supplier dictates which interface the chipsets are going to support. But the power advantage is a sufficiently compelling reason for device makers to quickly switch over to LPDDR3.
"I would anticipate a quick conversion of cell phones to LPDDR3. In tablets, so far Apple is the only supplier of any significance, so adoption depends solely on their moves," Handy said.
It's hard to predict when Samsung will ramp up production of LPDDR3, Handy said.
"Samsung has announced products lately that don't show up in production systems for over a year," Handy said.

TECHNOLOGY, Researchers Fashion Wearable Copper Wire Memory

[Photo: AIP Advances]We’ve already got wearable technology down when it comes to lighting and an augmented reality interface, but what about storage? Two NASA scientists have figured out a way to weave copper wire into a form for memory storage.
Jin-Woo Han and Meyya Meyyappan of the Center for Nanotechnology at NASA Ames Research Center developed the memory fiber. The design uses two 1-mm copper and copper oxide wires interweaved in a crisscross pattern sandwiched together by a small piece of platinum. The resulting structure forms a resistive memory circuit that can retain data, which can be read and rewritten when a current is applied, for more than 100 days.
This e-textile design follows the same basic crosshatched properties of real fabric, so it would be fairly easy to form wearable memory into any piece of clothing. Now all we need to do to make ourselves a real walking-talking mobile-computer is to put together all the mobile sensor, storage, processing, displays, and power source solutions into one package—that will hopefully look cooler than the “cyborgs” in Snow Crash.
