NEC makes magnetic flip flops
NEC has announced it managed to make a 1-bit Magnetic Flip Flop (MFF, as they like to call it). Unlike existing flip-flops, it does not need power to retain the value.
NEC suggests using such flip-flops instead of regular ones, and using MRAM instead of SRAM and you can make a system on a chip that does not need power to store data. MRAM is better than FLASH, says NEC, because of the unlimited write cycles.
NEC's MFF opereates at 1.2V or less, like regular flip-flops. The clock speed can be up to 3.5GHz.
