Two-Plane Copy-Back Program
Two-Plane Copy-Back Program is an extension of Copy-Back Program, for a single plane with 2112 byte page registers. Since the
device is equipped with two memory planes, activating the two sets of 2112 byte page registers enables a simultaneous program-
ming of two pages.

:
1. Copy-Back Program operation is allowed only within the same memory plane.
2. On the same plane, It’s prohibited to operate copy-back program from an odd address page(source page) to an even
address page(target page) or from an even address page(source page) to an odd address page(target page).
Therefore, the copy-back program is permitted just between odd address pages or even address pages.
