6.1.11

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 in the internal state machine 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

Section 6.1.9: Program

Suspend command and Section 6.1.10: Program Resume command paragraphs).

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.

After programming has started, Bus Read operations in the Bank being programmed output

the Status Register content, while Bus Read operations to the other Bank output the

contents of the memory array. See the section on the Status Register for more details.

Typical program times are given in

Table 18.

After the program operation has completed the memory will return to the Read mode, unless

an error has occurred. When an error occurs Bus Read operations to the Bank where the

command was issued will continue to output the Status Register. A Read/Reset command

must be issued to reset the error condition and return to Read mode.

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’.
