Title: Innovations by Julien Gasquez
Introduction
Julien Gasquez is an accomplished inventor based in Echirolles, France. He has made significant contributions to the field of memory technology, particularly in phase change memory systems. With a total of two patents to his name, Gasquez's work focuses on enhancing the efficiency and performance of memory devices.
Latest Patents
Gasquez's latest patents include a self-referenced and regulated sensing solution for phase change memory with an ovonic threshold switch. This invention outlines a method for operating a sense amplifier in a one-switch one-resistance (1S1R) memory array. The method involves generating a regulated full voltage and a regulated half voltage, which are applied to selected and unselected bit lines during read operations. This approach helps in inducing and compensating for sneak-path current by adjusting the applied read voltage based on the cell state of an accessed bit cell and the amplitude of the sneak-path current.
Another notable patent by Gasquez focuses on memory devices utilizing Ovonic Threshold Switching (OTS) selectors. These devices aim to bridge the gap between dynamic random-access memory (DRAM) and mass storage, making them suitable for high-end microcontrollers. The sense amplifier he developed generates an auto-reference that accounts for leakage currents of unselected cells and includes a regulation loop to compensate for voltage drops during read current sensing. This innovative design, built on a 28 nm fully depleted silicon-on-insulator (FDSOI) technology, provides robust performance across a wide range of memory array sizes.
