Introduction

Hiroshi Akasaki is a prominent inventor known for his significant contributions to semiconductor technology. He is based in Ome, Japan, and holds a total of 10 patents. His work has greatly influenced the development of reliable and efficient semiconductor devices.

Latest Patents

One of his latest patents is a semiconductor memory device designed to improve reliability when driving a word line while reducing access delay due to defect relief. This innovation prevents the multiple selection of a sub-word line of a normal memory mat and a sub-word line of a redundant memory mat by delaying the start of the redundant memory mat. Additionally, the shared circuit is eliminated, and the bit line length is reduced in the redundant memory mat, which decreases the read time of the bit lines and increases the signal amount. Consequently, the same activation timing of the sense amplifier can be utilized in both the normal and redundant memory mats. Another notable patent involves a semiconductor integrated circuit device, which includes methods for testing and manufacturing the device. This invention connects inputs of a control circuit to terminals for external operation control signals and timing signals used exclusively for testing, allowing for controllable changes in internal operation control signals during both test and normal operation modes.
