Title: The Innovative Mind of Toru Osajima
Introduction
Toru Osajima is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of integrated circuit design, holding a total of 11 patents. His work has been instrumental in advancing technology and improving the efficiency of electronic devices.
Latest Patents
One of Osajima's latest patents is focused on an integrated logic circuit and a hierarchical design method. This innovation involves modules disposed in a chip, which include a plurality of external buffer cells located along the module's periphery, and an internal circuit situated within these external buffer cells. The design allows for the input and output of signals between the internal circuit and the external circuit through the external buffer cells. Notably, the output-stage transistor of each external buffer cell is larger than the transistor size of the internal circuit. This configuration provides the external buffer cells with the capability to directly drive a transistor inside the chip through a wire that has the maximum Manhattan length of a module-disposed region on the chip. If the area allocated for the external buffer cells is insufficient, the module size can be enlarged, or repartitioning can be performed to ensure that the external buffer cells have adequate space.
