Multiplane copy back program
In addition to multiplane page program, the NAND04G-B2D and NAND08G-BxC devices
support multiplane copy back program.
A Multiplane Copy Back Program command requires exactly the same steps as a Multiplane
Page Program command, and must satisfy the same time constraints (see Section 6.4:
Prior to executing the multiplane copy back program operation, 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.
A traditional one (85h command, address insertion for the first plane, 11h command,
81h command, address insertion for the second plane, 10h command)
2.
ONFI 1.0 (85h command, address insertion for the first plane, 11h command, 85h
command, address insertion for the second plane, 10h command)
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
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 Section 6.12). Figure 17: Multiplane copy
back program provides a description of multiplane copy back program waveforms.
