Multiplane copy back program
In addition to multiplane page program, the NAND02G-B2D device supports multiplane
copy back program.
A Multiplane Copy Back Program command requires exactly the same steps as a multiplane
page program and must satisfy the same time constraints (see
program).
Prior to executing the multiplane copy back program, two single page read operations must
be executed to copy back the first page from the first plane and the second page from the
second plane.
Two different sequences are allowed for the multiplane copy back operation:
1.
2.
The EDC check is also performed during the multiplane copy back program. Errors during
multiplane copy back operations can be detected by performing a read EDC Status register
operation (see
If the multiplane copy back program fails, an error is signaled on bit SR0 of the Status
register. To know which page of the two planes failed, the Read Status Enhanced command
must be executed twice, once for each plane (see
description of multiplane copy back program waveforms.
