Better Than SST: Energy-Efficient Computer Memory Uses Voltage Rather Than Current

By using voltage instead of current, researchers say they have made major improvements to magnetoresistive random access memory - MRAM -  a faster, higher-capacity class of computer memory. Current, magnetic memory is based on spin-transfer torque (STT), which uses the magnetic property of electrons - spin - in addition to their charge. STT utilizes an electric current to move electrons to write data into the memory.   read more
