Program command
The program command is used to program a single word to the memory array.
If the block being programmed is protected, then the Program operation will abort, the data
in the block will not be changed and the Status Register will output the error.
Two Bus Write cycles are required to issue the Program command.
Once the programming has started, read operations in the bank being programmed output
the Status Register content.
During a Program operation, the bank containing the word being programmed will only
accept the Read Array, Read Status Register, Read Electronic Signature, Read CFI Query
and the Program/Erase Suspend command, all other commands will be ignored. A Read
Array command is required to return the bank to Read Array mode.
Refer to Dual Operations section for detailed information about simultaneous operations
allowed in banks not being programmed.
Typical Program times are given in
The Program operation aborts if Reset, RP, goes to V
guaranteed when the Program operation is aborted, the word must be reprogrammed.
See
the Program command.
Appendix
The first bus cycle sets up the Program command.
The second latches the address and data to be programmed and starts the
Program/Erase Controller.
