PURPOSE:To simplify the output control of a data memory by using the same channel for input data to a buffer memory. CONSTITUTION:An address from an address counter 44 for input is supplied through an address selector 45 synchronously with an input mode period corresponding to a command signal of a control circuit 20, and then mn pieces of data of the same channel are stored in the same addresses of respective memory elements 41-1-41-mn from a data memory 10. Further, data is outputted in a period T with the output of an address counter 46 for output. Thus, a chip selector 42 for input is advanced by mn in the period T and the address counter 46 for output is advanced by (n) to perform input/output control over the data. |
