Title: Nobuyuki Hayashi: Innovator in Memory Systems

Introduction

Nobuyuki Hayashi is a prominent inventor based in Hadano, Japan. He has made significant contributions to the field of data processing systems, particularly in memory technology. His innovative approach has led to advancements that enhance the efficiency of memory access.

Latest Patents

Hayashi holds a patent for a memory system that performs fast access to a memory location by omitting the transfer of a redundant address. This data processing system includes a processor LSI and a DRAM divided into banks, which increases the ratio of using a fast operation mode. By omitting the transfer of a row address to the DRAM, it minimizes the amount of logic external to the processor LSI. The processor LSI features row address registers that hold recent row addresses corresponding to the banks. A comparator checks whether the fast operation mode is possible by comparing the contents of the row address registers with an accessed address. This innovation allows for faster operations, particularly in block copy processing.
