Abstract
A semiconductor memory device includes first cell strings connected to first bit lines and second cell strings connected to second bit lines corresponding to the first bit lines, respectively. Data is stored in memory cells of the first cell strings, and the second cell strings are configured as a data non-storage region. At least one memory cell of each of the second cell strings is in a programmed state.
