Patent 10388388 was granted and assigned to Micron Technology on August, 2019 by the United States Patent and Trademark Office.
Apparatus, and methods of operating similar apparatus, might include an array of memory cells and a differential storage device configured to receive information indicative of a data value stored in a particular memory cell of the array of memory cells selected for a programming operation. The differential storage device might include a first non-volatile memory cell connected between a first isolation gate and a voltage node configured to receive a first voltage level, and a second non-volatile memory cell connected between a second isolation gate and the voltage node, and logic responsive to an indication of a loss of power to the apparatus and the information indicative of the data value stored in the particular memory cell to store data to the differential storage device, wherein a gate of the second non-volatile memory cell is connected to a gate of the first non-volatile memory cell.
