    摘要: A non-volatile semiconductor memory device and related method of determining a read voltage are disclosed. The non-volatile semiconductor memory device includes; a memory cell array including a plurality of memory cells, a read voltage determination unit configured to determine an optimal read voltage by comparing reference data obtained during a program operation with comparative data obtained during a subsequent read operation and changing a current read voltage to a new read voltage based on a result of the comparison, and a read voltage generation unit configured to generate the new read voltage in response to a read voltage control signal provided by the read voltage determination unit.
