Abstract
A semiconductor memory device includes a memory cell block. The memory cell block includes a plurality of n-type first MIS transistors with current passages connected in series. Each of the first MIS transistors includes a source, a drain, and a charge storage layer formed on a (001)-plane of a semiconductor substrate with a gate insulating film interposed therebetween and is configured to store data. A direction from the source to the drain in each of the first MIS transistors is set parallel to a [001]-direction or [010]-direction of the semiconductor substrate.
