Figure 7. Auto Page Program operation
The data is transferred (programmed) from the register to the selected
page on the rising edge of WE following input of the 10H command.
After programming, the programmed data is transferred back to the
register to be automatically verified by the device. If the programming
does not succeed, the Program/Verify operation is repeated by the
device until success is achieved or until the maximum loop number set in
the device is reached.
Auto Block Erase
The Auto Block Erase operation starts on the rising edge of WE after the Erase Start command D0H which
follows the Erase Setup command 60H. This two-cycle process for Erase operations acts as an extra layer of
protection from accidental erasure of data due to external noise. The device automatically executes the Erase
and Verify operations.
