Abstract
According to one embodiment, a semiconductor circuit includes a plurality of memories. The memories are connected to one another in series such that an output node of the memory of the first stage is connected to an input node of the memory of the second stage. The semiconductor circuit includes a test circuit that outputs test data to an input node of the memory of the first stage among the plurality of memories, and a comparison circuit that compares data output from an output node of the memory of the final stage among the plurality of memories with expectation value data.
