Abstract:
A memory including an array of non-volatile latch (NVL) cells and method of operating the same are provided. In one embodiment, each NVL cell includes a non-volatile portion and a volatile portion. The non-volatile portion includes a first non-volatile memory (NVM) device and a first pass gate transistor coupled in series between a first output node and a bitline true, and a second NVM device and a second pass gate transistor coupled in series between a second output node and a bitline complement. The volatile portion includes cross-coupled first and second field effect transistors (FET), the first FET coupled between a supply voltage (VPWR) and the first output node, and the second FET coupled between VPWR and the second output node. A gate of the first FET is coupled to the second output node, and a gate of the second FET is coupled to the first output node.
