Introduction

Katsumi Matsuno is a notable inventor based in Kokubunji, Japan. He has made significant contributions to the field of semiconductor devices, holding a total of 7 patents. His work focuses on enhancing the performance and efficiency of input circuits and data processing systems.

Latest Patents

One of his latest patents is an input buffer using a differential amplifier. This invention addresses the timing margin issues in input circuits for semiconductor devices, such as address buffers. By utilizing a differential amplifier, the design increases the operation speed of the input circuit. The address buffer includes a differential amplifier that receives an input signal and outputs a pair of differential signals. A latch circuit detects, latches, and outputs one of the paired differential signals that has changed first. The activation and inactivation of the differential amplifier are controlled by an N-channel MOS transistor through a Set signal. When activated, the differential amplifier generates a potential difference between the paired differential signals, and when inactivated, the signals go low.

Another significant patent is a data demultiplexer. This device comprises a write controller, a memory, an analyzing processing unit, and transfer control units. The write controller writes incoming packets into memory in the order of arrival and sends the write information to the analyzing processing unit. This unit analyzes the packets based on the write information and sends only the results to the transfer control units. The transfer control units then send data read from memory to the decoder in the order of packet arrival. This innovation aims to reduce the processing load on the analyzing processing unit.
