摘要：
A plurality of logic circuits access a DRAM block by way of an access circuit. The operation clock for the DRAM block is set at a higher frequency than the system clock for the logic circuits. Outputs of a first bit width from the logic circuits are subjected to serial/parallel conversion into data of a second bit width and the data is written into the DRAM block.
