Title: Innovations of James B. MacArthur
Introduction
James B. MacArthur is a notable inventor based in Santa Clara, CA (US). He has made significant contributions to the field of integrated circuits, holding a total of 4 patents. His work has been instrumental in advancing memory design technologies.
Latest Patents
One of his latest patents is titled "Configurable memory design for masked programmable logic." This invention involves a mask programmable integrated circuit that includes a read-only memory (ROM), a random access memory (RAM), and a controller. The controller connects to both the ROM and RAM, sensing reset conditions and directing either a clear of the RAM or a preload of ROM contents to the RAM. This preload can occur after a successful self-test of the RAM. The RAM is designed with variable word lengths and depth sizes, allowing it to operate in various modes. The integrated circuit also features two multiplexers (MUX). The first MUX is positioned between the RAM and ROM, selectively coupling either ROM data or built-in self-test (BIST) data to its output. The second MUX connects the first MUX to the RAM, allowing for the selection of either the first MUX output or a data input. This innovative design enables the emulation of ROM, preloaded RAM, or look-up table logic functions, as well as conventional RAM. Additionally, the BIST feature allows for RAM testing without external support.
