Abstract
In a non-volatile semiconductor memory device outputting a data value determined according to a majority rule by reading-out data from each memory cell for an odd number of times, an odd number of latch circuits, each of which comprises a capacitor for selectively holding a voltage of each of the data read-out from the memory cell for the odd number of times in sequence, is provided. The capacitor of each latch circuit is connected in parallel after the capacitor of each latch circuit selectively holds the voltage of each of the data read-out from the memory cell for the odd number of times in sequence, and the data value is determined by the majority rule based on a composite voltage of the capacitor of each latch circuit connected in parallel.
