Title: Flash memory device and method for driving the same

Abstract: Provided are a flash memory device and a method of driving the same for improving reliability of stored set information. The method of driving the flash memory device includes applying power to the flash memory device, the flash memory device having a memory cell array for storing set information regarding operation environment settings, where the set information includes at least one bit. The method further includes performing an initial read operation on the memory cell array and judging a status of data, corresponding to the set information, read during the initial read operation to determine whether the initial read operation has passed or failed. Each bit of the set information is extended to n bits (where n is an integer equal to or greater than 2). The n bits are respectively stored in different input/output regions in the memory cell array.
