Two-Plane Copy-Back Program Operation
Multi Page Copy-Back Program is an extension of Copy-Back Program, for a single plane with 4328byte data
registers. Since the device is equipped with two memory planes, activating the two sets of 4328 byte data
registers enable a simultaneous programming of two pages. Same page address (PA0 to PA5) within two
districts has to be selected.
