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.
