ABSTRACT:
The data detecting apparatus may provide a voltage comparison unit that compares a reference voltage, associated with a specific data bit from among a plurality of data bits stored in a memory cell, with a threshold voltage in the memory cell, a detection unit that detects a value of the specific data bit based on a result of the voltage comparison unit, and a decision unit that decides whether the specific data bit is successfully detected based on whether an error occurs in the detected data. The detection unit may re-detect a value of the specific data bit based on detection information with respect to at least one of an upper data bit and a lower data bit in relation to the specific data bit, in response to a result of the decision unit.
