Latest Patents

One of Igarashi's latest patents is a magnetoresistive memory device. This device includes first and second layer stacks, each comprising a first ferromagnetic layer with a magnetization directed in a first direction. Above this layer is a non-magnetic first conductive layer, followed by a second ferromagnetic layer that has a magnetization directed in a second direction, which differs from the first. Additionally, a first insulating layer is positioned on the upper surface of the second ferromagnetic layer, with a third ferromagnetic layer above it. Notably, the second ferromagnetic layer of the second layer stack is thicker than that of the first layer stack.

Another significant patent involves a memory device that features a first wiring extending in a first direction and a second wiring that intersects it. A memory cell is situated between these wirings and includes a resistive memory element and a switching element connected in series. An insulating region surrounds the memory cell, which consists of a first insulating part adjacent to the resistive memory element and a second insulating part next to the switching element. The second insulating part is designed to have a higher thermal conductivity than the first.
