Abstract
A self-synchronous FIFO memory device () has a structure in which n self-synchronous data transmission lines (-) are arrayed in parallel. An input control section () selects one of the n self-synchronous data transmission lines, and mediates the reception and delivery of a first transfer request signal, a first acknowledge (transfer instruction) signal and data between the selected self-synchronous data transmission line and a self-synchronous data transmission line of a preceding-stage section. Further, an output control section () selects one of the n self-synchronous data transmission lines, and mediates the reception and delivery of a second transfer request signal, a second acknowledge (transfer instruction) signal and data between the selected self-synchronous data transmission line and a self-synchronous data transmission line of a succeeding-stage section.
