Abstract: According to one embodiment, a transceiver includes a sampler, a pipeline, and a transmission circuit. The sampler takes a data signal received from a host at a timing based on a data strobe signal received from the host. The pipeline transfers the data signal taken by the sampler using at least a clock signal, different from the data strobe signal, as a drive signal. The transmission circuit acquires and transmits a data signal having passed through the pipeline.

Abstract: According to one embodiment, a timing adjustment circuit for a memory interface is presented. The circuit is provided with a gate circuit, an original gate signal generation circuit, a high impedance prevention unit, an impedance control unit and a gate leveling circuit. The gate circuit performs gating of a data strobe signal outputted from a memory. The original gate signal generation circuit generates an original gate signal based on information of a read latency and a burst length. The high impedance prevention unit to prevent the data strobe signal from being in a high impedance state. The impedance control unit controls execution and release of operation of the high impedance prevention unit. The gate leveling circuit outputs a timing adjusted gate signal to the gate circuit based on the original gate signal and the data strobe signal.

Abstract: According to one embodiment, a phase adjuster operates according to a phase difference between a first clock signal and a second clock signal. The adjuster includes an adjustment driving element and a crosstalk driving element. The adjustment driving element drives an input signal and generates an adjusted signal. The crosstalk driving element generates an in-phase and/or a reverse-phase crosstalk signal in parallel to the adjusted signal when the phase difference occurs between the first clock signal and the second clock signal.
