Freescale Brings New Memory Chip to Market || The Mac Observer

Freescale Semiconductor is the first company to bring a new type of memory chip, called MRAM (Magnetoresistive Random Access Memory), to the marketplace. The memory chips benefit from faster response times than current Flash-based chips, lower power requirements, and can also be written to an unlimited number of times. Flash-based memory can be written to between 100,000 and a million times before failing.
