Abstract
A MONOS type non-volatile semiconductor memory device has a memory cell array. The memory cell array includes a plurality of pairs of bit line and control line. These bit line-control line pairs are parallel to the channel on the substrate. The memory cell array also includes a plurality of memory cells. Each memory cell has a two-transistor configuration. A certain number of memory cells are disposed between the bit line and control line of each pair. These memory cells are connected in series, and connected with the bit line and control line alternately. The first gate electrode and second gate electrode in the memory cell are formed in strips in a direction perpendicular to the channel.
