Abstract
According to one embodiment, a semiconductor integrated circuit includes a logic circuit and a memory macro. The memory macro includes: a memory cell array including a memory bit cell; an output buffer; a sense amplifier configured to output data read from the memory cell array based on a first clock signal; a write driver configured to apply a write voltage; and a first register circuit that configured to fetch first input data based on a second clock signal, output the first input data to the write driver based on the second clock signal in a write operation, and outputs the first input data to the output buffer based on the first clock signal in a scan test of the logic circuit.
