Samsung's phase change RAM will go into mass production starting in June. These chips represent a big evolutions from traditional RAM. The PRAM chips can rewrite data without having to erase what's already on there first allowing them to perform up to 30x quicker and last 10x longer than traditional flash memory.

Phase-change Random Access Memory (PRAM) uses a material that turns crystalline when heated. The clrystalline bits represent the logical "1" in the binary system of computers, while amorphous areas (bits) represent logical "0"
PRAM is also more scalable than any other memory architecture being researched and features the fast processing speed of RAM for its operating functions combined with the non-volatile features of flash memory for storage.
