  • Publication number: 20110060952
    Abstract: The semiconductor integrated circuit including a memory macro includes a memory cell unit, input data holding units, and output data holding units. The input data holding units hold one of values of input data signals and a scan value depending on a scan control signal in accordance with an operating clock. The output data holding units hold one of values held by the input data holding units and data values stored by the memory cell unit depending on a test control signal in accordance with a phase different from a phase to operate the input data holding units. Further, the input data holding units and the output data holding units are alternately connected in series, and one input data holding unit is arranged at the top. A value held by one output data holding unit is transmitted to another input data holding unit arranged at a subsequent stage of the one output data holding units as the scan value.
