He has made significant contributions to the field of memory technology, particularly in scalable magnetoresistive random access memory (MRAM). With a total of 2 patents to his name, Savtchenko's work has the potential to influence the future of data storage.
Latest Patents
Savtchenko's latest patents include a method of writing to scalable magnetoresistance random access memory elements. This method involves switching a scalable magnetoresistive memory cell by applying current waveforms to a magnetoresistive memory device, which is sandwiched between a word line and a digit line. The process allows for the effective magnetic moment vector of the device to rotate by approximately 180 degrees. The device comprises N ferromagnetic layers that are anti-ferromagnetically coupled, with N being adjustable to modify the magnetic switching volume.
Another significant patent is for a scalable magnetoresistive tunneling junction memory cell. This invention features a fixed ferromagnetic region with a magnetic moment vector that remains stable in the absence of an applied magnetic field. It also includes an electrically insulating material that forms a magnetoresistive tunneling junction, along with a free ferromagnetic region that can be oriented parallel or anti-parallel to the fixed region. The free ferromagnetic region consists of N ferromagnetic layers that are anti-ferromagnetically coupled, allowing for an increase in the effective magnetic switching volume of the MRAM device.
