Title: Innovations of Stanley Jeh-Chun Ma
Introduction
Stanley Jeh-Chun Ma is a notable inventor based in Gloucester, CA. He has made significant contributions to the field of content addressable memory (CAM) technology. With a total of 9 patents to his name, Ma's work focuses on enhancing the efficiency and performance of memory circuits.
Latest Patents
One of his latest patents is the "Matchline Sense Circuit and Method." This invention discloses a matchline sense circuit designed to detect a rising voltage on a matchline of a CAM array. The circuit precharges a matchline to ground before activating a current source to supply current and raise the matchline voltage. A reference matchline sense circuit generates a self-timed control signal to maintain the current supply for a predetermined duration. This innovative approach reduces power consumption by precharging the matchlines to ground instead of the supply voltage, VDD. Additionally, it increases the speed of the matchline sensing operation by sensing the rise of the matchline voltage to an n-channel transistor threshold potential.
Another significant patent is the "Multiple Match Detection Circuit and Method." This invention provides a multiple matchline sense circuit that detects single, multiple, or no match conditions during a search-and-compare operation of a CAM. The circuit compares the rising voltage rate of multiple matchlines to that of a reference matchline, generating a multibit result that represents one of three conditions. It also produces a self-timed control signal to conclude the search-and-compare operation and set the circuit to a precharge state.
