Magnetic Random Access Memory



Michael L. Schneider, P. G. Mather


Magnetic Random Access Memory (MRAM) possesses a unique combination of attributes that provide considerable benefits over those available with conventional memory technology. Here we discuss the state-of-the-art of MRAM, from parts currently in production to development efforts underway. A promising future for MRAM is emerging as new write techniques for even higher-density and lower-power modes of operation are developed and optimized. While high density is highly desirable in any data-storage medium, MRAM differentiates itself from the magnetic data storage discussed in this chapter, since the primary focus is operation as a high-speed RAM with fast read and write times and extremely reliable performance coupled with nonvolatility that the magnetic nature of the storage element provides. MRAM provides a nonvolatile high-speed memory array that can be paired directly with a microprocessor, rather than a system for storing extensive volumes of information.
