Abstract:
A method is disclosed to operate a memory device. The method includes, prior to overwriting a first unit of data at a location in a memory device with a second unit of data, determining if more energy is required to write the second unit of data than to write the second unit of data with at least one sub-unit thereof having bits that are inverted. If it is determined that less energy is required to write the second unit of data with the at least one sub-unit thereof having bits that are inverted, the method further includes overwriting the first unit of data with a modified second unit of data with the at least one sub-unit thereof having bits that are inverted, in conjunction with writing at least one bit memory for indicating a location in the modified unit of data of the sub-unit of data having the inverted bits.
