Title: Clarisse Ducruet: Pioneering Innovations in Magnetic Memory Technology

Introduction

Clarisse Ducruet, an innovative inventor based in Grenoble, France, has made significant contributions to the field of magnetic memory technology. With a remarkable portfolio of five patents, her work has the potential to revolutionize data storage solutions, particularly in the realm of magnetic random access memory (MRAM).

Latest Patents

Among her latest patents, Clarisse developed a method for fabricating a magnetic tunnel junction suitable for MRAM cells. This invention involves a structure comprising a first ferromagnetic layer, a tunnel barrier layer, and a second ferromagnetic layer. A notable aspect of her technique is the deposition of a layer of metallic magnesium (Mg), which is later oxidized to form magnesium oxide (MgO) as part of the tunnel barrier. The fabrication process is executed multiple times to ensure a robust and effective tunnel barrier layer composed of at least two MgO layers.

Another significant contribution by Clarisse is her patent for a low-power magnetic random access memory cell designed for thermally assisted write operations or spin-torque transfer (STT) based write operations. This MRAM cell incorporates a magnetic tunnel junction with a top electrode, enhancing magnetic performance with a magnetoresistance greater than 100%. Importantly, her design reduces power consumption compared to conventional MRAM cells, making it a more efficient option for modern technology.
