Phase Change Memory

IBM has announced a breakthrough in their phase change memory (PCM). This is non volatile memory like flash. It keeps the data when the power is turned off. The big news is that this memory is 100 times faster than flash.

The worst case latency for the memory is 10 micro seconds. This statistic is 100 times the performance of flash memory. The PCM has had a capacity breakthrough as well. Previously only 1 bit per cell was reliable. IBM is now working with a configuraiton that works with 4 bits per cell. PCM memory size is going up soon.

IBM envisions this memory to be used all over the place. It can be in PCs for ultra fast startup. It can be used in the cloud. It can even be used in mobile phone applications.
