Two firms have doubled the capacity of phase-change memory, a likely replacement for flash.
By Kate Greene
Over the past decade, flash memory has changed the electronics landscape, giving us robust storage in tiny devices such as iPods and cell phones. As chip sizes shrink, however, engineers know there will be limits to flash performance, and they have been eyeing a replacement technology called phase-change memory. Today, Intel announced a research advance that doubles the storage capacity of a single phase-change memory cell. This new approach is also implemented in the chip via algorithms so that it won't add cost to the existing phase-change memory fabrication process.
