Extended write modes for non-volatile static random access memory architectures having word level switches

Abstract

Disclosed herein is a method of performing a non-volatile write to a memory containing a plurality of volatile memory cells grouped into words, with each volatile memory cell having at least one non-volatile memory cell associated therewith. The method includes steps of a) receiving a non-volatile write instruction including at least one address and at least one data word to be written to that at least one address, b) writing the at least one data word to the volatile memory cells of a word at the at least one address, and c) writing data from the volatile memory cells written to during step b) to the non-volatile memory cells associated to those volatile memory cells by individually addressing those non-volatile memory cells for non-volatile writing, but not writing data from other volatile memory cells to their associated non-volatile memory cells because those non-volatile memory cells are not addressed.
