10T Non-Volatile Static Random-Access Memory

摘要

A memory including an array of nvSRAM cells and method of operating the same are provided. Each nvSRAM cell includes a volatile charge storage circuit, and a non-volatile charge storage circuit including exactly one non-volatile memory (NVM) element, a first transistor coupled to the NVM element through which data true is coupled to the volatile charge storage circuit, a second transistor coupled to the NVM element through which a complement of the data is coupled to the volatile charge storage circuit and a third transistor through which the NVM element is coupled to a positive voltage supply line (VCCT). In one embodiment, the first transistor is coupled to a first node of the NVM element, the second transistor is coupled to a second node of the NVM element and the third transistor is coupled between the first node and VCCT. Other embodiments are also disclosed.
