    摘要: A semiconductor device which can reduce the peak value of the rush current generated during a transition from resume mode to normal mode. The semiconductor device has a plurality of daisy-chained memory modules. Each of the memory modules includes a memory array, a switch for controlling, in resume mode, source voltage supply to a constituent element of the memory module, and a delay circuit which receives a resume control signal ordering a transition from resume mode to normal mode and outputs a resume control signal delayed from the inputted resume control signal to the memory module of the next stage.

    摘要: A semiconductor integrated circuit device includes an SDRAM module operating in synchronization with a clock signal, a logic circuit transmitting data with the SDRAM module for effecting necessary processing, a direct memory access circuit taking in and transferring an externally applied signal in synchronization with the clock signal corresponding to an operation clock of the SDRAM module, and a selector selecting either the output signal of the logic circuit and the output signal of the direct memory access circuit in accordance with a test mode instructing signal for application to the SDRAM module. A test of a synchronous memory can be performed by externally making fast and direct access to the synchronous memory without an influence of a skew in a signal.
