A built-in self test circuit includes a capture register storing data transmitted from a memory device, an operation controller controlling operation of the memory device and the capture register, a hold controller executing a hold operation to stop a read operation and a write operation of the memory device by transmitting a hold signal to the operation controller, and a test control circuit controlling the operation controller to transmit a capture signal so that the capture register stores the data to the capture register.
