MRAM is a memory (RAM) technology that uses electron spin to store information. It has been dubbed “the ideal memory” – potentially combining the density of DRAM with the speed of SRAM and non-volatility of FLASH memory or hard disk, and all this while consuming a very low amount of power.
MRAM can resist [...]

“Ultra-rapid pulses of polarized light fired from lasers, new tests show, can outperform conventional magnetic data writers by as much as two orders of magnitude.
Researchers at Radboud University Nijmegen in the Netherlands think they’ve found another candidate. In laboratory experiments, they used laser light to write data to a magnetic hard drive at very high [...]
