+ - After 38 years, a new type of memory to hit market

JoeD writes: It's been a long haul for phase change memory, but the goal is in sight. Numonyx is already shipping samples of phase change memory (PCM) chips to customers and will start shipping PCM chips commercially later this year.

Why will the world want PCM? Performance, says Numonyx CTO Ed Doller. PCM chips can survive tens of millions of read-write cycles, he said, or far more than flash. Reading data to PCM chips takes 70 to 100 nanoseconds, or as fast as NOR flash. Data can be written to the chips at a rate of 1 megabyte a second, or equivalent of NAND flash. There is also no erase cycle, making it similar to DRAM.

I have not yet begun to byte!
