Title: Thomas Riordan and His Memory and FPGA Innovations.

Introduction

Thomas Riordan is an inventor associated with Los Altos, California. His patent work includes memory-cell and field-programmable gate array (FPGA) designs, and he is associated with Aril Computer Corporation. His listed portfolio includes 3 patents.

Latest Patents

Riordan’s listed inventions include a multi-port static random-access memory (SRAM) design with a buffered read port and p- and n-channel pass gates connected to the same write bit line. The design separates writing from reading: transmission gates connect the cell to write bit lines, while a buffered read path carries the stored signal to a read bit line. Its transistor arrangements are intended to support standard-cell or macro layouts and operation at ultra-low supply voltages.

Another listed invention is an FPGA configurable cell using p- and n-channel pass gates connected to the same bit line. In configuration mode, transmission gates allow the RAM cell to communicate with bit lines; in mission mode, they remain off while the FPGA performs its configured logic functions. The design also describes using stored configuration data in switching fabric and logic blocks, with rows of RAM cells storing a look-up table and performing first-level multiplexing.
