Abstract
A packet switch provides a write signal when processing of a packet in a FIFO memory is started, and outputs the write signal to the preceding stage. Meanwhile, the writing side manages whether a FIFO memory in the next stage is in a write-enabled state, and renders it into a write-disabled state in response to writing of a packet. The writing side also renders the FIFO memory of the next stage into a write-enabled state in response to a write-enable signal from the next stage.
