Figure 16. Two-Plane Copy-Back Program Operation
Note
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 four 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.
3. Two-plane copy-back page program into plane 0&2(or plane 0&3, or plane 1&2, or plane 1&3) is prohibited.
.
Any command between 11h and 81h is prohibited except 70h and FFh.
