ABSTRACT:
There is provided a serial access system semiconductor storage device capable of reducing access time and decreasing consumption current. A memory cell array including a plurality of memory cells and shift registers and having a plurality of latch circuits connected in series are provided. The shift registers once hold data, received from the memory cell array 1 via a bit line in a read operation, in the latch circuits and serially output the held data in the order in which the latch circuits are arranged. The latch circuits sense-amplify the data stored in the memory cells inside the memory cell array.
