Freescale Semiconductor has started volume production of the world's first Magnetoresistive Ram.
The memory chips combine the speed of traditional Ram with the magnetic storage capability of a hard drive, allowing it to retain data when power is switched off.
Traditional static Ram and dynamic Ram chips used for computer memory require constant power to retain data.
Flash memory for use in digital cameras and portable music players does not require constant power, but offers significantly lower data transfer rates.
Until recently PDAs, for instance, used only static Ram, causing the units to erase all data if the batteries became depleted.
Magnetoresistive Ram will enable the development of new classes of electronic devices by allowing for smaller form factors, lower cost, lower power consumption and enhanced system performance.
Freescale said that the memory would find applications in gaming, networking, security and data storage.
The devices are available in volume from today. The current model operates on 3.3v and offers 35-nanosecond read and write cycle times. It is manufactured using 200mm lithography technology in Arizona.
