Program and verify phase
In the program and verify phase the four words that were loaded in the load phase are
programmed in the memory array and then verified by the Program/Erase Controller. If any
errors are found, the Program/Erase Controller reprograms the location. During this phase
the Status Register shows that the Program/Erase Controller is busy, the Status Register bit
SR7 is set to ‘0’, and that the device is not waiting for new data (Status Register bit SR0 set
to ‘1’). When Status Register bit SR0 is set to ‘0’ the program and verify phase has
terminated.
Once the verify phase has successfully completed, subsequent pages in the same block
can be loaded and programmed. The device returns to the beginning of the load phase by
issuing one bus write operation to latch the address and the first of the four new words to be
programmed.
Exit phase
Finally, after all the pages have been programmed, write one bus write operation to any
address outside the block containing the start address, to terminate the load and program
and verify phases.
Status Register bit SR7 set to ‘1’ and bit SR0 set to ‘0’ indicate that the Quadruple
Enhanced Factory Program command has terminated. A full Status Register check should
be done to ensure that the block has been successfully programmed. See
Register
If the program and verify phase has successfully completed the memory returns to read
mode. If the P/EC fails to program and reprogram a given location, the error is signaled in
the Status Register.
