IBM’s 90nm phase-change memory tech unveiled
June 30, 2011IBM says it has produced 90-nanometer-size processors that can store multiple bits of data per cell over time without the data becoming corrupted. The multi-level phase-change memory (PCM) technology should lead to solid-state chips that can match NAND flash disks' 1TB capacities, but are about 100 times faster and feature a much longer lifespan, claims the company.
