ABSTRACT:
High-speed operation is achieved without increase in a circuit current and unstable operation of data strobe signal level due to collision between data strobe signals. Each of RAMs11aand11boutputs a data signal DQ and a data strobe signal DQS indicative of an output timing of the data signal. RAM11aincludes a strobe signal control unit15athat determines whether RAM11bconnected in parallel with the RAM11ais in a read state or not, and delays an output start timing of data strobe signal DQS when the RAM11bis in the read state. Strobe signal control unit15aof the RAM11acontrols output start timing so that a latter half portion of a preamble period of the data strobe signal DQS to be output coincides with a postamble period of the data strobe signal DQS output by the RAM11b.
