Phase change memory produces very fast read and write speeds at lower power than conventional NOR and NAND flash memory, and allows for bit alterability normally seen in RAM.
Phase change memory has many of the advantages of NAND and NOR flash memory as well as other RAM memories - allowing data to be read at RAM speeds while lowering the cost and power consumption levels by reducing the large amounts of RAM often used in today's digital applications.
NAND flash vendors have been exploring a variety of alternatives including spin-torque MRAM, nanocrystal memory, phase change memory and resistive memory.
