Abstract
In a clock synchronous memory like a double data rate synchronous DRAM, a register is provided which is capable of setting a value (advanced latency) for specifying an input or entry cycle for a read or write command. Further, a timing adjustment register (124, 125) for delaying a signal by a predetermined cycle time according to the advanced latency set to the register is provided on a signal path in a column address system, which is formed between a column address latch circuit (110) and a column decoder (116).
