Method and apparatus for non-destructive access of volatile and non-volatile data in a shadow memory array |
摘要 |
Circuitry, including a non-volatile dynamic random access memory cell, a sense amplifier and a data latch affords non-destructive accessing and comparison of the data stored within the volatile and non-volatile portion of the memory cell. In certain applications, it is desirable to restore the volatile data to the volatile portion of the memory cell, and the circuitry also provides a path for such restoration.
