Magnetoresistive RAM has powerful attractions

Having been first to commercialise Magnetoresistive Random Access Memory (MRAM) technology, in 2006, Freescale Semiconductor has extended is portfolio to include 1Mbit, 2Mbit and 4Mbit versions for more flexibility and performance in wide-ranging applications.

Freescale’s MRAM portfolio now includes the 1Mbit MR0A16A, 2Mbit MR1A16A, and 4Mbit MR2A16A products in commercial, industrial and extended temperatures from -40°C to 105°C.

MRAM uses magnetic materials combined with conventional silicon circuitry to deliver the speed of SRAM with the non-volatility of Flash in a single device of unlimited endurance. By combining the best features of non-volatile memory and RAM at a competitive price, Freescale’s MRAM devices enable instant-on capability and power-loss protection in new classes of intelligent electronic devices.

As an easy-to-use, non-volatile memory, MRAM is being adopted by leading OEMs seeking flexible and reliable data storage without battery backup. Earlier this year, for example, Freescale announced that Siemens’ Industry Automation division had used the MR2A16A to support battery-less storage of process data for the SoftPLC software-programmable logic controller used in its Simatic Multipanel touchscreen interface for industrial automation systems.
