摘要
A semiconductor integrated circuit has a memory circuit having memory cells, a first register, a second register, a register selection circuit having an input to which an output of the first register and an output of the second register are connected, a memory bypass circuit which is located between a first switching circuit and a second switching circuit, and connected to the inputs and the outputs of the memory circuit. The register selection circuit is switched to the output signals of the first register when performing testing by way of the memory circuit, and switched to output signals of the second register when performing testing by way of the memory bypass circuit.
