In addition, flash memory is making its way into more enterprise and client computer applications, both as a stand alone storage device and as a cache memory and system accelerator.
Going forward Toshiba expects to bring the new memory element to STT-MRAM cache memory for mobile processors integrated into smartphones and tablet PCs, and will promote accelerated research and development toward that end.

This modeled application of an STT-MRAM integrating the memory as cache memory and recorded a two-thirds reduction in power consumption by a standard mobile chip set carrying out standard operating functions, a result confirming that the new MRAM element has the lowest power consumption yet achieved.

TOKYO-Toshiba Corporation (TOKYO: 6502) today announced that the company has developed a prototype memory element for a spin transfer torque magnetoresistive random access memory (STT-MRAM) that achieves the world's lowest1 power consumption yet reported, indicating that it has the potential to surpass the power consumption efficiency of SRAM as cache memory.

The Pre Rec (retro cache) feature continuously records and stores up to five seconds of footage in cache memory to help prevent missed shots of breaking news, while a second trigger and servo zoom control on the built-in handle makes it easy to record while holding the camera at low or high angles.

The company has introduced products for this industry before but it appears that the time is right for these products as well as hybrid HDDs (HDDs that contain some cache flash memory for frequently used data) to become wide-spread in computer architectures.

The Duron also includes a larger on-chip memory cache than the K6-2, and AMD's Enhanced 3DNow instructions, designed to boost multimedia performance.
If flash falls to magnetic memory, cache will fall with it, because MRAM could replace both kinds of memory in cell phones.

And while DRAM is strong enough to handle complex software, it's slow: When the PC needs to crunch numbers, it must resort to far faster memory cache, also called SRAM (static random access memory).
And while DRAM is strong enough to handle complex software, it ain't so swift: When the PC needs to crunch numbers, it must resort to far faster memory cache, also called SRAM (static random access memory).
Likewise, if DRAM ever loses out to magnetic memory, cache chips will decline alongside it.
For that, it must rely on cache but cache has the same memory-loss problems as DRAM.
For years the storage hierarchy has been basically the same: memory, cache, disk.
But so will the addition of one megabyte of level 3 cache, as well as the Double Data Rate SDRAM memory with a 133-MHz system cache standard on all models.
