SEMICONDUCTOR STORAGE DEVICE

摘要

A semiconductor memory solves performance degradation of a memory device caused by performance of memory functions different depending on a position of a memory cell array. In the memory cell array including memory cells in each of which a memory element is electrically connected to one of a source and a drain of a cell transistor, the cell transistor includes at least two types with different current driving capability according to a position in the memory cell array.
