Title: John Stuart Mullin, Sr: Innovator in Memory Technology
Introduction
John Stuart Mullin, Sr. is a notable inventor based in Boise, ID (US), recognized for his contributions to memory technology. He holds a total of 6 patents, showcasing his innovative spirit and technical expertise in the field.
Latest Patents
One of his latest patents is the 256 Meg dynamic random access memory. This invention comprises a plurality of cells organized into individual arrays, with the arrays being structured into 32 Meg array blocks, which are further organized into 64 Meg quadrants. Sense amplifiers are strategically positioned between adjacent rows in the individual arrays, while row decoders are placed between adjacent columns. The design includes multiplexers in certain gap cells to transfer signals from I/O lines to datalines. Additionally, a comprehensive data path is established, which includes array I/O blocks that respond to the datalines from each quadrant to output data to a data read multiplexer, data buffers, and data driver pads. The write data path features a data input buffer and data write multiplexers for providing data to the array I/O blocks. A power bus is integrated to minimize the routing of externally supplied voltages, completely ring each of the array blocks, and ensure gridded power distribution within them. The power supplies are organized to match their output to the demand, maintaining a desired ratio of power production capability and decoupling capacitance. Furthermore, a power-up sequence circuit is included to control the chip's power-up process. Redundant rows and columns are also provided, along with the necessary circuitry to logically replace defective rows and columns with operational ones. The invention supports various types of test modes, enhancing its functionality.
