The Momentus XT drives include a flash memory cache inside of the hard disk drive.

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.
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.

If flash falls to magnetic memory, cache will fall with it, because MRAM could replace both kinds of memory in cell phones.
If flash falls to magnetic memory, cache will fall right with it because MRAM could replace both kinds of memory in cell phones.
Likewise, if DRAM ever loses out to magnetic memory, cache chips will decline alongside it.
For years the storage hierarchy has been basically the same: memory, cache, disk.
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.

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).

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.
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.

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.
Flash memory offers fast ways to cache and serve up digital content to support high usage virtual machine environments.
For that, it must rely on cache but cache has the same memory-loss problems as DRAM.
Inside is a dysfunctional family of three separate kinds of memory chips DRAM, cache and flash thrown together out of weakness.

Write caching would store data to be written on the HDD in flash memory initially until enough data was in the flash cache to do an efficient write to the HDD disks.

Of course, the exploit that they've actually released is completely harmless, but it demonstrates that the CPU cache can be "poisoned" to let folks read and write into the otherwise protected SMRAM memory.
