Title: Shingo Hanatani: Innovator in Semiconductor Technology

Introduction

Shingo Hanatani is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of 3 patents. His work focuses on enhancing the performance and efficiency of programmable logic arrays and integrated circuits.

Latest Patents

One of Hanatani's latest patents is a **Programmable Logic Array**. This invention features a precharge circuit that operates separately from precharge transistors. The design allows for one of the wirings connecting memory cell transistors to connect to a power supply voltage simultaneously with the precharge transistors. This innovation improves charge share tolerance and prevents output variation in the programmable logic array's AND plane.

Another notable patent is for a **Semiconductor Integrated Circuit**. In this design, a precharge transistor is responsible for precharging a bus, while a discharge transistor discharges it. A push-pull driver, consisting of a p-channel MOS transistor and an n-channel MOS transistor, sets the bus potential to either 'H' level or 'L' level. A detection circuit identifies which component, either the discharge transistor or the push-pull driver, is active. When the push-pull driver is engaged, a control circuit disables the precharge transistor, optimizing the circuit's performance.
