SEMICONDUCTOR INTEGRATED CIRCUIT, MEMORY SYSTEM AND ELECTRONIC IMAGING DEVICE

摘要

A semiconductor integrated circuit (100) fetches and transfers read data from a DDR-SDRAMs (110, 120) operating in synchronization with a clock. The semiconductor integrated circuit is provided with read buffers (104, 105) for fetching and transferring the read data from the DDR-SDRAMs (110, 120); latch timing control circuits (102, 103) for controlling latch timing wherein the read buffers (104, 105) fetch the read data from the DDR-SDRAMs (110, 120), based on a data strobe signal from the DDR-SDRAMs (110, 120); and a read timing control circuit (106) for controlling read timing wherein the read buffers (104, 105) transmit read data, based on latch timing of the latch timing control circuits (102, 103).
