Abstract
A memory device comprising memory cells having volatile and non-volatile memory portions. The volatile memory portion of each cell includes circuitry for performing RAM functions while the non-volatile memory portion comprises circuitry defining pre-coded data. The memory device comprises a mechanism to operate an initialization sequence, which sets the initial state of the volatile memory portion of each memory cell to the pre-coded data defined in the associated non-volatile memory portion. The initialization sequence allows the initial state of each memory cell's volatile portion to be re-established after power has been applied to the memory device.
