Latest Patents

One of Siyeon Cho's latest patents is a magnetic memory device and method of operating the same. This innovative device features a loop-type magnetic track with a first part and a second part arranged in a counterclockwise direction. It includes a first conductive line on the top surface of the first part and a second conductive line on the bottom surface of the second part. The magnetic track is composed of a lower magnetic layer, a spacer layer, and an upper magnetic layer that are sequentially stacked. Each conductive line is made of heavy metal and is designed to generate spin-orbit torque from the current flowing through it. This spin-orbit torque enables the movement of magnetic domains in the magnetic track in either a clockwise or counterclockwise direction.

Another notable patent by Cho is for a three-dimensional (3D) semiconductor memory device. This device comprises a substrate that includes a cell array region, a connection region, and a block selection region. It features a stack structure with horizontal layers that are vertically stacked on the substrate. Each horizontal layer contains electrode portions extending in a first direction and a connecting portion that connects these electrode portions in a second direction, which is perpendicular to the first. The device also includes block selection gate electrodes that intersect the sidewalls of the electrode portions.
