Patent ID: 7660155

Claim:
A method of driving a non-volatile memory device, the method comprising: providing power to the non-volatile memory device having a memory cell array that stores initial setting data for setting an operating environment of the non-volatile memory device; performing an initial read operation on the memory cell array; and setting the operating environment of the non-volatile memory device using the initial setting data that is read during the initial read operation, wherein the initial setting data stored in the memory cell array includes main data including information about the operating environment to be set and an indicator corresponding to the main data, the indicator includes at least one of start information having a first predetermined value and end information having a second predetermined value of the main data, wherein the setting the operating environment of the non-volatile memory device comprises: sensing the start information included in the indicator from the data read during the initial read operation by detecting information having a value corresponding to the first predetermined value; and controlling to provide the main data corresponding to the indicator to an internal circuit of the non-volatile memory device when the start information is sensed.
