6.2.3

Unlock Bypass command

The Unlock Bypass command is 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.

Once the Unlock Bypass command has been issued the bank enters Unlock Bypass mode. When in

Unlock Bypass mode, only the Unlock Bypass Program and Unlock Bypass Reset commands are valid.

The Unlock Bypass Program command can then be issued to program addresses within the bank, or the

Unlock Bypass Reset command can be issued to return the bank to Read mode. In Unlock Bypass mode

the memory can be read as if in Read mode.

6.2.4

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

Bank where the command was issued outputs the Status Register. See the Program command for details

on the behavior.

6.2.5

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.
