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 write buffer by this command.
Enhanced Buffered Program Confirm command
The Enhanced Buffered Program Confirm command is used to confirm an Enhanced
Buffered 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
This results in a faster total programming time.
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
for details on the behavior.
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 Enhanced Buffered 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.
