Abstract
The state of a prescribed internal column address signal bit is selectively fixed according to a mode switch circuit. A specific row address signal bit is transmitted instead of a column address signal bit under the control of the mode switch circuit. Thus, a semiconductor memory device having a plurality of storage capacities and address spaces is realized with a single chip structure.
