IBM and TDK will work together to develop higher-capacity, more compact Magnetoresistive RAM (MRAM) chips.
MRAM uses tiny magnetic fields rather than electrical charges to store data. Like flash memory, it retains data without the need for electrical power.
One potential market for MRAM is for computers that can be turned on instantly, without the need to load software into memory each time on start up. However, the MRAM chips currently on the market have capacities of only a few megabits, adequate for embedded control systems but not enough for modern PCs.
TDK and IBM hope that increases in capacity will make MRAM more attractive to cellphone and handheld computer manufacturers.
