Fast, non-volatile magnetic RAM is being developed in Germany

Siemens, Bosch and government laboratories in Germany are developing Magnetic RAMs (MRAMs) which could be the ideal memory – dense, non-volatile, fast to read and write, low power and with infinite read/write cycles.
MRAMs can solve the increasing problem of the slow access times of hard disks. It would eliminate boot-up time in PCs, allow much quicker downloading of material over the Internet and it could replace flash memory in mobile phones and portable computers.
O One gigabit MRAMs are considered feasible with sub-10mW power consumption and access times of 40/50ns.
“We are working on MRAMs in the Central Research Department at Siemens and at the BMBF – the government’s research department,” Hans Pieter Bette, executive v-p of the memory division at Infineon Technologies, told EW.
MRAMs are based on the same ‘spin electronics’ technology which is used for giant magneto-resistive (GMR) heads in disk drives.
