Freescale Semiconductor announced that the first commercial magnetoresistive random access memory (MRAM) device is now in volume production. According to the company, its 4Mbit MRAM product is a fast, non-volatile memory with unlimited endurancea combination of characteristics not available in any other individual semiconductor memory product. The device is built on a foundation of technology protected by more than 100 Freescale patents, including toggle-bit switching.

MRAM uses magnetic materials combined with conventional silicon circuitry to deliver the speed of SRAM with the non-volatility of Flash in a single, high endurance device. Freescale's commercialization of this technology could hasten new classes of electronic products offering advances in size, cost, power consumption and system performance.

Freescale's first commercial MRAM product, called the MR2A16A, is appropriate for a variety of commercial applications such as networking, security, data storage, gaming and printers. The part is engineered to be a reliable, economical, single-component replacement for battery-backed SRAM units, the company said. The device also could be used in cache buffers, configuration storage memories and other applications that require the speed, endurance and non-volatility of MRAM.

Housed in a 10.16mm TSOP type-II RoHS package, the MR2A16A is a commercial temperature range, 3.3V device featuring 35ns read and write cycle times. It is an asynchronous memory organized as 256K words by 16bits. An industry standard SRAM pinout arrangement allows for system design flexibility without bus contention.
