A memory unit is provided herein. Two non-volatile devices are used to store a logic state of the memory unit into the non-volatile devices. Although a power supply for the memory unit is shut down, the non-volatile devices still keep the data stored therein. The present invention not only has an advantage of high speed operation of a static random access memory (SRAM), but also has a function for storing data of a non-volatile memory.
