Latest Patents

Sim is credited with 1 patent: “Non-volatile memory device and electronic system including the same.” The invention describes a substrate with a cell array region and an extension region, along with a stepped mold structure made of alternating gate electrodes and insulating layers. A channel structure passes through the mold structure in the cell array region, while a cell contact structure passes through it in the extension region. The contact structure touches both the side and top surfaces of an uppermost gate electrode, with its side-contacting portion narrower than its top-contacting portion. This arrangement addresses the design of contacts within a non-volatile memory device.
