Magnetic memory chips reach the market

Tash Shifrin

Freescale Semiconductor has put the first commercially available magnetic memory chip on the market.

The new MR2A16A is a four megabit Magnetoresistive Random Access Memory (Mram) chip, which uses magnetic materials combined with conventional silicon circuitry.

MRam is a non-volatile memory technology that can store information for extended periods without power. It stores data by applying a magnetic field that causes memory cells to enter one of two magnetic states, in a break from conventional memory technologies – such as flash and DRam (dynamic Ram) – which use an electric charge to store data.

MRam is seen as a potential replacement for flash memory in mobile devices, and could also replace volatile DRam (dynamic Ram) in PCs.

Freescale said its new chip was designed to offer a reliable, economical, single-component replacement for battery-backed Sram products and could be used in commercial applications such as networking, security, data storage, gaming and printers.
