Introduction

Hideharu Toyomoto is a notable inventor based in Itami, Japan. He has made significant contributions to the field of processor technology, holding a total of 3 patents. His work focuses on enhancing the efficiency and capacity of memory systems in processors.

Latest Patents

One of Toyomoto's latest patents is the Memory-contained processor. This innovation features a processor that includes a cache memory with an enlarged storage capacity while minimizing area increases. The design incorporates both SRAM (Static Random Access Memory) and DRAM (Dynamic RAM) cache memories, which are connected to the processor through a dedicated processor bus. This configuration allows for data transfer via an internal transfer bus that has a larger width than the processor bus.

Another significant patent is the Refresh control circuit. This circuit is designed for processors connected to dynamic random access memory through an address bus, data bus, and control signal lines. It outputs a refresh control signal at predetermined intervals to maintain the integrity of the dynamic random access memory. The refresh control circuit consists of control circuitry and an address generator, which latches a value from the control circuitry. The refresh address is then modified based on the N-th power of 2, where N corresponds to the number of memory banks in the dynamic random access memory.
