ABSTRACT:
Logic circuits access a memory block by way of an access circuit. The memory block, which is formed of a mixed configuration of DRAMs and an SRAM, realizes the desired memory space. A data output register is provided at the output side of the SRAM so as to synchronize data output timing from the DRAMs with data output timing from the SRAM.
