USER’S MANUAL
Up to eight unique 64-byte pages are programmed simultaneously in eight separate
array blocks of each of the two CMF modules. Each of the pages being programmed
simultaneously is located at the same block offset address, ADDR[17:25].
Erasing is performed on one or more of the selected block(s) simultaneously.
