NVE Corporation announced today that it has been notified by the U.S. Patent and Trademark Office (USPTO) of the expected grant of a patent relating to magnetothermal Magnetoresistive Random Access Memory (MRAM).

NVE has been notified that the patent, titled "Magnetic Memory Layers Thermal Pulse Transitions," will issue today. The patent is number 7,266,013 and covers inventions by Dr. James M. Daughton and Dr. Arthur V. Pohm. The grant is in addition to similarly-titled patent numbers 7,177,178 and 7,023,723.

MRAM is an integrated-circuit memory which is fabricated with nanotechnology and which uses electron spin to store data. MRAM may have the potential to combine many of the best attributes of different types of semiconductor memories.

Magnetothermal MRAM is a next-generation MRAM technology that uses a combination of ultra-fast magnetic fields and heat pulses, both from electrical current, to reduce the energy required to write data and allow reduction of the memory cell size while maintaining thermal stability.
