ABSTRACT:
A semiconductor memory device for serially outputting previously loaded data from an integral memory is disclosed herein. The device is configured to output head data from a predetermined location in the memory by latching the head data directly from a common bus. In a preferred embodiment the head data is latched by a single latch circuit. In a method of the invention, the head data is transferred directly from a predetermined memory address onto a common bus. A latch circuit then latches the head data from the common bus. The latched head data is next presented to an output buffer. Thereafter, data is presented in a serial form from a plurality of serial registers to the output buffer.
