Abstract
A non-volatile memory device according to example embodiments includes at least one NAND flash memory and a memory controller configured to control the NAND flash memory. The memory controller comprises a bit counter configured to count a number of first binary digit of each of first to N-th readout page data, the first to N-th readout page data being respectively read by first to N-th test read voltages, a register configured to store first to N-th count values with respect to the first to N-th readout page data output from the bit counter, and a read voltage adjuster configured to compare the first to N-th count values to determine a read voltage, where N is an integer greater than 1.
