ABSTRACT:
A semiconductor memory device with shift registers used for a video RAM, including a memory cell array, bit lines, and word lines, a pair of shift registers, and transfer gate circuits arranged between the bit lines and the shift registers. Each parallel data transfer circuit is provided between the shift registers for transferring parallel data between the shift registers, so that high-speed reading and writing of data for a CRT display is realized.
