Abstract:
1. A method of reading configuration data related to an operating environment of a flash memory device, the flash memory device comprising a memory cell array which stores the configuration data, the method comprising: setting a read time of the configuration data to differ from a read time of normal data; and reading the configuration data wherein the read time of the configuration data and the read time of the normal data each comprises at least one of a page buffer reset time, a bit line precharge time, a bit line develop time and a sensing time, wherein the read time of the configuration data further comprises an additional time by regulating at least one of the page buffer reset time, the bit line precharge time, the bit line develop time and the sensing time of the configuration data, and wherein the read time of the configuration data differs from the read time of the normal data by as much as the additional time of the configuration data.
