Title: Wataru Yamaguchi: Innovator in Semiconductor Technology
Introduction
Wataru Yamaguchi is a notable inventor based in Kodaira, Japan. He has made significant contributions to the field of semiconductor technology, holding two patents that focus on enhancing data processing devices. His work emphasizes low power consumption and efficient interfacing operations.
Latest Patents
Yamaguchi's latest patents include a semiconductor data processing device and a data processing system. These inventions aim to achieve low power consumption during both standby and operational states. The semiconductor data processing device is designed to connect a non-volatile storage device to a general-purpose bus of a host system. It intelligently enters active or standby states based on the general-purpose bus's status. In standby mode, the device halts the internal clock signal and applies a substrate bias voltage to minimize potential sub-threshold leak currents. This bias voltage is also directed to the central processing unit and rewritable non-volatile memory, which stores the control program executed by the CPU. The central processing unit processes data in units of n bits or below, while the interface controller and data transfer controller handle parallel data in units of 2n bits.
