Title: Lee Hirsch - Innovator in Memory Technology

Introduction

Lee Hirsch is a notable inventor based in Mountain View, CA. He has made significant contributions to the field of memory technology, particularly with his innovative patent related to dual-port read/write RAM.

Latest Patents

Hirsch holds a patent for a "Dual-port read/write RAM with single array." This invention features a single-array memory that employs a novel storage cell, providing dual read/write access via either an 'A'-side or a 'B'-side. The unique circuit design allows for read current to be borrowed during the writing process into the cell. Additionally, asymmetrical read/write delay circuitry is incorporated to prevent overwriting the contents of a storage cell during the read-to-write transition. The row-selection decoders utilize Schottky-clamping diodes, which provide equivalent oscillation-damping capacitance at the base of the selected-row driver transistor. This single-array memory can be effectively used as part of a single-chip VLSI four-port register file, allowing simultaneous reading and/or writing of registers from any of the two read ports or two write ports. Unidirectional busses connect each storage cell to each of the four ports.
