Intel and Numonyx held a press conference earlier today to discuss a phase change memory (PCM) breakthrough many years in the making. The companies have been jointly exploring the possibilities of multi-layered or stacked PCM cell arrays, and have finally been able to demonstrate a 64Mb test chip that has the ability.These vertically integrated memory cells, dubbed PCMS (phase change memory and switch), will be comprised of one PCM element layered with an Ovonic Threshold Switch (OTS) in a true cross point array. Intel and Numonx PCMS, Phase Change Memory and Switch PCM memory uses material state as an identifier, either crystalline or amorphous, to determine the state of a cell (1 or 0) and... Read more...
Intel, after recently reviewing its memory technology roadmap, speculated that phase change memory (PCM) will possibly be available by the end of the year. Phase change memory can run faster and be manufactured smaller then DRAM memory and as a result Intel believes it may possibly one day replace flash memory. Flash memory can become unreliable after as many as 10,000 write cycles where as phase change memory can go through as many as 100 million write cycles before a noticeable degradation. This week Intel privately shared parts of it roadmap for memory technologies through 2008. Revealed was that Intel's progress on phase-change memory, shortened as usually PCM or PRAM, will...
