Abstract:
A nonvolatile static random access memory (SRAM) device includes a pair of cross-coupled, complementary metal oxide semiconductor (CMOS) inverters configured as a storage cell for a bit of data and a pair of magnetic spin transfer devices coupled to opposing sides of the storage cell. The magnetic spin transfer devices are configured to retain the storage cell data therein following removal of power to the SRAM device, and are further configured to initialize the storage cell with the retained data upon application of power to the SRAM device.
