Abstract
A semiconductor memory device includes memory cells, a memory cell array, a contact region, and first contact plugs. The memory cells include a control gate and a current path. The memory cells are arranged in the memory cell array in the first direction. The contact region is adjacent to the memory cell array in a second direction orthogonal to the first direction. A terminal portion on one end of the control gate is drawn onto the contact region from within the memory cell array. Each of the first contact plugs is formed on the control gate located in the contact region. The first contact plugs are located so as to alternately sandwich a first axis in the first direction.
