Program command
The Program command can be used to program a value to one address in the memory
array 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.
Programming can be suspended and then resumed by issuing a Program Suspend
command and a Program Resume command, respectively (see
Suspend command
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 given.
During the program operation the memory will ignore all commands. It is not possible to
issue any command to abort or pause the operation. Typical program times are given in
Table 8: Program, Erase times and Program, Erase Endurance
operations during the program operation will output the Status Register on the Data
Inputs/Outputs. See the section on the Status Register for more details.
After the program operation has completed the memory will return to the Read mode, unless
an error has occurred. When an error occurs the memory will continue 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 memory from ’0’ to ’1’.
