Abstract

The invention relates to a method for converting volatile memory cells to non-volatile memory cells with minimal modifications. There is included a volatile memory cell which is modified to permanently retain data by using one refresh port to transmit an active low voltage signal and configuring one terminal of the storage transistor to receive either an active high or low voltage signal.
