PROGRAM Command

The PROGRAM command can be used to program a value to one address at a time. The

command requires four bus WRITE operations. The final WRITE operation latches the

address and data, and starts the program/erase controller.

If the address falls in a protected block, then the PROGRAM command is ignored, the

data remains unchanged. The status register is never read and no error condition is giv-

en.

During the PROGRAM operation, the memory will ignore all commands. It is not possi-

ble to issue any command to abort or pause the operation. Typical program times are

given in READ CFI QUERY Command. READ operations during the PROGRAM opera-

tion will output the status register on the data I/Os. (See Registers.)

After the PROGRAM operation has completed, the memory returns to read mode, un-

less an error has occurred. When an error occurs, the memory continues to output the

status register. A READ/RESET command must be issued to reset the error condition

and return to read mode.

Note that the PROGRAM command cannot change a bit set at 0 back to 1. One of the

ERASE commands must be used to set all the bits in a block, or in the whole device,

from 0 to 1.

UNLOCK BYPASS Command

The UNLOCK BYPASS command is used in conjunction with the UNLOCK BYPASS

PROGRAM command to program the memory. When the access time to the device is

long (as with some EPROM programmers), considerable time saving can be made by

using these commands. Three WRITE operations are required to issue the UNLOCK BY-

PASS command.
