ABSTRACT:
An initial verify read operation is performed after each programming pulse. The verify voltage starts at an initial verify voltage for the first word line and increases for each word line that is verified up to a maximum verify voltage. A second verify read operation is then performed after the program/verify operation. The second verify read operation uses a verify voltage that is substantially close to the maximum verify voltage used during the program/verify step.
