Abstract
A non-volatile memory device increases a number of word lines and a storage capacity using a multi level cell. The non-volatile memory device addresses a problem of self-boosting not being adequately generated due to the increased number of word lines. The non-volatile memory device includes a memory cell array configured to have first memory cells for storing first bit information coupled to third word lines except a first word line adjacent to a drain select line and a second word line adjacent to a source select line, and second memory cells coupled to the first word line and the second word line. The second memory cells store second bit information that is smaller than the first bit information.
