Unlock Bypass Chip Erase command
The Unlock Bypass Chip Erase command can be used to erase all memory blocks at a time.
The command requires two bus write operations only instead of six using the standard
Chip Erase command. The final bus write operation starts the program/erase controller. The
Unlock Bypass Chip Erase command behaves in the same way as the Chip Erase
command: the operation cannot be aborted, and a bus read operation to the memory
outputs the status register (see
Unlock Bypass Write to Buffer Program command
The Unlock Bypass Write to Buffer command can be used to program the memory in fast
program mode (see
The command requires two bus write operations less than the standard Write to Buffer
Program command.
The Unlock Bypass Write to Buffer Program command behaves in the same way as the
Write to Buffer Program command: the operation cannot be aborted and a bus read
operation to the memory outputs the status register.
The Write to Buffer Program Confirm command is used to confirm an Unlock Bypass Write
to Buffer Program command and to program the N+1 words/bytes loaded in the write buffer
by this command.
Unlock Bypass Reset command
The Unlock Bypass Reset command can be used to return to read/reset mode from unlock
bypass mode. Two bus write operations are required to issue the Unlock Bypass Reset
command. Read/Reset command does not exit from unlock bypass mode.
