Latest Patents
Etsuko Iwamoto holds a patent for a semiconductor integrated circuit device having circuit inspection. This invention features an integrated circuit that includes latch circuits positioned on both the input and output sides of an object circuit, which is designed to measure delay time. The device incorporates a variable delay circuit that can arbitrarily delay a timing signal, either supplied from an external source or generated internally by an instruction from outside. The timing signal, along with a delay signal produced by the variable delay circuit, serves as clock signals for the latch circuits. Additionally, the signal passing through the variable delay circuit is fed back to the input side, forming an oscillation circuit. This allows for the automatic generation of a signal delayed by a desired time within the semiconductor integrated circuit based on the timing signal.
