Abstract
A non-volatile static random access memory (NVSRAM) device includes a volatile circuit and a non-volatile circuit. Under normal operations when an external power is supplied, the volatile circuit can provide fast data access. When the power supply is somehow interrupted, the non-volatile circuit can provide data backup using an inverter circuit and a non-volatile erasable programmable memory (NVEPM) circuit, thereby retaining data previously stored in the volatile circuit.
