ABSTRACT:
A FIFO memory device using a serial pointer consists of first and second memory cell arrays, a row decoder for selecting a word line, first and second write registers for storing data, each write register consisting of registers, and a serial write pointer for serially selecting each register. The serial write pointer consists of pointers corresponding to the first and second write registers. The row decoder is located between the first memory cell array and the second memory cell array. In the device, in adjacent registers in each write register, the shift direction of one register indicated by said serial write pointer is opposed to the shift direction of the other register.
