Toshiba says its 1GB MRAM chips are "almost ready," we're ready now

MRAM from Toshiba
It wasn't long ago that IBM promised to unleash its racetrack MRAM (magnetoresistive RAM) on a power and speed-hungry computing public, but now Toshiba says its 1GB MRAM chips are "almost ready". The chips use Spin-RAM (STT-RAM) and Toshiba fully expects them to take over where DRAM left off by 2015. They say their new chips use about 10 percent the energy used by DRAM and, like MRAM is supposed to do, retain memory even after the power supply has been cut off. So what does this mean? Instant boot-up, fast access times, and super-low power consumption. While MRAM has been announced by others, capacities and speeds promised by this 1GB jobby from Toshiba will certainly make things worthwhile.

IBM's next gen flash storage to feature spinning electrons

by Nilay Patel, posted Aug 20th 2007 at 11:52PM

You don't usually think of IBM in the context of flash memory innovation, but all those processors Big Blue cranks out require some kind of cache , and the company's new joint venture with TDK is designed to create the next-gen of flash, using a technology called "spin torque transfer" that will allow scaling beyond 65nm. STT-RAM, as it's called, uses a current to "spin-polarize" electrons and align their magnetic fields to represent 1s and 0s. Intel and others have invested heavily in a rival next-gen tech called phase change, but IBM says STT is faster and may last longer. Obscure system-on-a-chip next-gen flash memory format war, here we come!
