Write to Buffer Program Confirm command
The Write to Buffer Program Confirm command is used to confirm a Write to Buffer Program
command and to program the N+1 words/bytes loaded in the program buffer by this
command.
Enhanced Buffer Program Confirm command
The Enhanced Buffer Program Confirm command is used to confirm an Enhanced Buffer
Program command and to program the 256 words loaded in the buffer.
Unlock Bypass command
The Unlock Bypass command is used to place the device in Unlock Bypass mode. When
the device enters the Unlock Bypass mode, the two initial unlock cycles required in the
standard program command sequence are no more needed, and only two write cycles are
required to program data, instead of the normal four cycles (see
Table
Unlock Bypass command is consequently used in conjunction with the Unlock Bypass
Program command to program the memory faster than with the standard program
commands. When the cycle time to the device is long, considerable time saving can be
made by using these commands. Three Bus Write operations are required to issue the
Unlock Bypass command.
When in Unlock Bypass mode, only the Unlock Bypass Program, Unlock Bypass Block
Erase, Unlock Bypass Chip Erase, and Unlock Bypass Reset commands are valid:
In Unlock Bypass mode the memory can be read as if in Read mode.
Unlock Bypass Program command
The Unlock Bypass Program command can be used to program one address in the memory
array at a time. The command requires two Bus Write operations, the final write operation
latches the address and data and starts the Program/Erase controller.
The Program operation using the Unlock Bypass Program command behaves identically to
the Program operation using the Program command. The operation cannot be aborted, a
Bus Read operation to the memory outputs the Status Register. See the program command

16-bit mode

10). This results in a faster total programming time.
The Unlock Bypass Program command can be issued to program addresses
within the memory.
The Unlock Bypass Block Erase command can then be issued to erase one or
more memory blocks.
The Unlock Bypass Chip Erase command can be issued to erase the whole
memory array.
The Unlock Bypass Write to Buffer Program command can be issued to speed up
programming operation.
The Unlock Bypass Reset command can be issued to return the memory to Read
mode.
