... M29W400BT, M29W400BB Unlock Bypass Command. The Unlock Bypass command is used in conjunction with the Unlock Bypass Program command to program the memo- ry. When the access time to the device is long (as with some EPROM programmers) considerable time saving can be made by using these com- mands. Three Bus Write operations are required to issue the Unlock Bypass command ...
