Two-Plane Block Erase
Basic concept of Two-Plane Block Erase operation is identical to that of Two-Plane Page Program. Up to two blocks, one from each
plane can be simultaneously erased. Standard Block Erase command sequences (Block Erase Setup command(60h) followed by
three address cycles) may be repeated up to twice for erasing up to two blocks. Only one block should be selected from each plane.
The Erase Confirm command(D0h) initiates the actual erasing process. The completion is detected by monitoring R/B pin or Ready/
Busy status bit (I/O 6).
Two-plane erase operations can be executed by dividing the memory array into plane 0~1 or plane 2~3 separately.
For example, two-plane erase operation into plane 0 and plane 2 is prohibited. That is to say, two-plane erase operation into plane 0
and plane 1 or into plane 2 and plane 3 is allowed.

NOTE : Two-plane block erase into plane 0&2(or plane 0&3, or plane 1&2, or plane 1&3) is prohibited.
NOTE : It is an example for two-plane page program into plane 0~1(In this case, A
plane 2 ~3 is same. two-plane page program into plane 0&2(or plane 0&3, or plane 1&2, or plane 1&3) is prohibited.
