ERASE Operations
If the time remaining to complete the operation is less than the suspend latency, the de-
vice completes the operation and clears the flag status register bits 2 or 6, as applicable.
Because the suspend state is volatile, if there is a power cycle, the suspend state infor-
mation is lost and the flag status register powers up as 80h.
During an ERASE SUSPEND operation, a PROGRAM or READ operation is possible in
any sector except the one in a suspended state. Reading from a sector that is in a sus-
pended state will output indeterminate data. The device ignores a PROGRAM com-
mand to a sector that is in an erase suspend state; it also sets the flag status register bit 4
to 1, program failure/protection error, and leaves the write enable latch bit unchanged.
The commands allowed during an erase suspend state are shown in the Operations Al-
lowed/Disallowed During Device States table. When the ERASE resumes, it does not
check the new lock status of the WRITE LOCK REGISTER command.
During a PROGRAM SUSPEND operation, a READ operation is possible in any page ex-
cept the one in a suspended state. Reading from a page that is in a suspended state will
output indeterminate data. The commands allowed during a program suspend state in-
clude the WRITE VOLATILE CONFIGURATION REGISTER command and the WRITE
ENHANCED VOLATILE CONFIGURATION REGISTER command.
It is possible to nest a PROGRAM/ERASE SUSPEND operation inside a PROGRAM/
ERASE SUSPEND operation just once. Issue an ERASE command and suspend it. Then
issue a PROGRAM command and suspend it also. With the two operations suspended,
the next PROGRAM/ERASE RESUME command resumes the latter operation, and a sec-
ond PROGRAM/ERASE RESUME command resumes the former (or first) operation.
