Title: Innovations by Inventor Ioan Tudosa in Spin-Transfer Torque Magnetic Memory
Introduction
Ioan Tudosa is a notable inventor based in Milpitas, California, with a significant contribution to the field of memory technology. He holds a total of four patents, showcasing his commitment to advancing the capabilities of magnetic random access memory (MRAM) systems. His innovative works primarily focus on spin-transfer torque magnetic memory, which offers enhanced performance and energy efficiency.
Latest Patents
Tudosa's latest patents include a revolutionary memory system that features a thermally stable perpendicular magneto tunnel junction (MTJ) and a method for its manufacturing. This invention involves a spin-transfer torque magnetic random access memory (STTMRAM) element designed to store information based on the magnetic orientation of a free layer. The STTMRAM element comprises a first perpendicular free layer (PFL) that includes a first perpendicular enhancement layer (PEL) and is supported by a seed layer. Furthermore, the design introduces a barrier layer situated on the first PFL, topped with a second perpendicular reference layer (PRL) that contains a second PEL. A capping layer is also included, which is positioned above the second PRL.
Additionally, Tudosa has developed a second patent in the realm of spin-transfer torque MRAM, which features a composite fixed layer situated on a substrate, complemented by a tunnel layer formed upon it and a composite free layer on the tunnel barrier layer. The significance of this invention lies in the magnetization direction of both the composite free and fixed layers, which is arranged to be substantially perpendicular to the plane of the substrate. This composite structure consists of multiple repetitions of a bi-layer unit that merges a non-magnetic insulating layer with a magnetic layer, finely tuned to achieve preferred perpendicular magnetization.
