PURPOSE: An operation method is provided to improve the stability of a device by using reprogrammed cam cell data after reading out newly reprogrammed cam cell data. CONSTITUTION: A nonvolatile memory device includes a general cell part and a cam cell part. A fail check operation of a general cell part is executed(320). Cam cell data saved in the cam cell part is read out(360). The cam cell part is reprogrammed. The program, read-out, and erase operation of a device are executed by using the operation voltages of a device(370). |
