A technique of using an ordinary static random access memory (SRAM) array for a programmable nonvolatile (NV) memory is proposed. The parallel NV writing of the entire array is achieved by simply applying high-voltage stress to the power supply terminal, after storing inverted desired data in the static random access memory (SRAM) array. Successful 2 kbit NV writing is demonstrated using a device-matrix-array (DMA) test element group (TEG) fabricated by 0.18μm technology.
