Abstract
A semiconductor memory device includes a memory cell; and a page buffer including a sensing circuit that is coupled to the memory cell through a bit line. The page buffer includes a first transistor included in the sensing circuit; and a second transistor not included in the sensing circuit. A cross-sectional dimension of a first contact which is coupled to the first transistor and a cross-sectional dimension of a second contact which is coupled to the second transistor are different from each other. The cross-sectional dimension of the second contact is smaller than the cross-sectional dimension of the first contact.
