Title: Innovator Spotlight: Nicholas J. Sawyer

Introduction

Nicholas J. Sawyer is a notable inventor based in London, United Kingdom. With two patents to his name, he has made significant contributions to the field of memory technology, particularly in the design and development of advanced RAM systems.

Latest Patents

Nicholas's latest invention is a Multiport RAM with programmable data port configuration. This innovative RAM allows for programmable configuration of data ports. In the case of a multiport RAM, it provides independent programmable configuration for each port. This design incorporates a single programmable RAM cell that can be utilized across various data port configurations. By doing so, it effectively reduces the number of combinations necessary in a standard cell library or gate array required to implement every possible configuration.

In one embodiment of his invention, Nicholas details a dual-port RAM equipped with a decoder, as well as an input multiplexer and output multiplexer for each data port. The input multiplexer provides different selectable mappings of a RAM input word of various sizes to the input bit lines of the respective data port. Similarly, the output multiplexer offers various selectable mappings of the RAM output bit lines to the RAM output word. The decoder, receiving configuration programming bits, determines the appropriate size of the RAM input and output word for each port, utilizing column addressing bits to select the appropriate mapping from the multiplexers. During RAM write operations, decoding circuitry ensures that the non-addressed input bits are disabled, enhancing efficiency and precision.
