Memory Upgrade: Spin-torque MRAM
Company: Everspin Technologies
Availability: Test samples available now
Processor speeds get more attention but many computers are actually limited by the performance of their memory. A new data storage technology, spin-torque magneto-resistive RAM, combines the best features of the two most commonly used forms of memory: DRAM and flash. DRAM, used as short-term memory in laptops and servers, is fast and packs data densely into tiny spaces. But flash, used to store data in cell phones and some hard drives, requires less energy and is “non-volatile”— it retains information even when powered off. These new modules store bits of data as magnetic states in a way that offers fast, non-volatile storage. They could make cloud computing services more responsive.
