Abstract
A buffer circuit includes: a register array including registers in a plurality of stages; and a control circuit configured to rearrange a plurality of pieces of received data in the register in a determined transfer order and to control the register array to sequentially output the plurality of pieces of received data as one piece of transfer data when all the received data is stored, wherein the control circuit controls the register array to store stored data in each register in a preceding stage when the register array outputs the received data, and the control circuit determines a write register in accordance with the transfer order when the register array newly stores the received data and controls the register array to store data stored in the write register in a following stage of the write register and to store the new received data in the write register.
