摘要： In an LSI that determines timing of DRAM refresh by a refresh timer to synchronize an external I/O signal and DRAM refresh timing with each other, a circuit configuration capable of controlling a value of the refresh timer by a CPU at arbitrary timing is employed. Alternatively, a circuit configuration capable of controlling the value of the refresh timer at arbitrary timing by an external terminal, or a circuit configuration capable of controlling the refresh timing directly from the external terminal without through the refresh timer.
