Abstract: PURPOSE:To surely supervise a data delaying time and to hold it at a fixed level or below by adding a multiplexing means and a multiplexing separating means to the input side and output side of an FIFO memory between a test pattern generating/checking circuit and them. CONSTITUTION:To a multiplexing circuit 30, input data and the test pattern of the output of a test pattern generating/checking circuit 20 are added. The clock of the two-fold input data speed is added, a time division multiplexing is executed, the clock is inputted to an FIFO memory 10, and it is temporarily accumulated. The clock of a several-fold input clock is added to the CKO of the memory 10, the clock is made high-speed, and the time-division-multiplexed data and test pattern are outputted. The outputs are added to a multiplexing separating circuit 40, they are separated into output data and the test pattern, and the test pattern is added to the circuit 20. The time of a difference between the time of starting a test pattern output and the time of inputting it is obtained as the data delaying time. When the delaying time exceeds the fixed level, a master reset is applied to the memory 10.
