Abstract
To provide a data fetch circuit, which reliably cuts off transmission of a high impedance state of a data strobe signal even if a manufacture condition or an operation condition is changed, and a control method thereof. The data fetch circuit includes an RL measuring partmeasuring a latency measurement value RLB from an input of a read instruction signal RD to a valid edge of a data strobe signal DQS and an RL count comparing partoutputting a BL count start signal BST giving an instruction of a cancel of the cut-off of the data strobe signal DQS after standing by during the time based on the latency measurement value RLB in accordance with an input of a delay read instruction signal RDD.
