Latest Patents

Li Li's latest patents include a three-dimensional memory device containing tubular blocking dielectric spacers. This invention involves forming an alternating stack of insulating layers and sacrificial material layers over a substrate. Memory openings are created through this stack, and annular recesses are formed by laterally recessing the sacrificial material layers around each memory opening. A tubular aluminum oxide spacer is formed at the periphery of each annular recess, followed by the selective deposition of a tubular silicon oxycarbide spacer. These spacers undergo an oxidation process to convert them into tubular silicon oxide spacers. Additionally, tubular charge storage spacers are formed on the inner sidewalls of the silicon oxide spacers, culminating in the formation of a vertical semiconductor channel over the respective vertical stack of tubular charge storage spacers within each memory opening. The sacrificial material layers are then removed to create backside recesses, where electrically conductive materials are deposited to form conductive layers.

Another notable patent is for an adaptive erase of a storage device. This invention includes systems, methods, and devices that enable adaptive erasure in a storage device. The method involves performing a series of memory operations, including read and erase operations on specified portions of non-volatile memory devices. The erase operations are conducted using a first set of parameters established prior to execution. The method also includes updating erase statistics corresponding to multiple operations and establishing a second set of erase parameters based on a comparison with an erasure performance threshold.
