Dual Operation
Dual Operation
Multipartition architecture of the device enables reading from one partition while a
PROGRAM or ERASE operation is occurring in another partition. This is called read-
while-program and read-while-erase, respectively.
Only status reads are allowed from a partition that is busy programming or erasing. If
non-status reads are required from a partition that is busy programming or erasing, the
PROGRAM or ERASE operation must be suspended first.
