Title: The Innovations of Mitchell A. Stones

Introduction

Mitchell A. Stones is a notable inventor based in Phoenix, AZ. He has made significant contributions to the field of technology, particularly in the development of advanced memory systems. With a total of 3 patents to his name, his work has had a lasting impact on CPU performance and memory access efficiency.

Latest Patents

One of his latest patents is the "N+0.5 wait state programmable DRAM controller." This invention improves CPU system performance by reducing the time required to complete a DRAM access for microprocessors such as the 386DX, 386SX, and 80286. By incorporating a programmable DRAM controller, it allows consecutive DRAM accesses to average N+0.5 processor wait states. The innovation involves measuring wait states in processor clock time units, which enables earlier assertion of RAS and CAS signals, thus facilitating quicker data transfer to and from the DRAM.

Another significant patent is the "Combination asynchronous cache system and automatic clock tuning device." This invention features an automatic clock tuning device that includes a pulse generator, a counter, a unit delay tree, a comparing device, and a feedback path. The device allows for the cache data/tag Write Enable (WE) signal to be clocked off the falling edge of a delayed version of the System Clock (SCLK). This innovation ensures that the CPU address/data hold time is maintained without introducing unnecessary wait states.
