Abstract: A three-dimensional memory device includes a substrate and a stack structure including alternating conductive layers and dielectric layers disposed on the substrate, and a memory string structure extending vertically through the stack structure. The memory string structure includes a conductive pillar and a storage layer disposed between the conductive pillar and the stack structure and surrounding the conductive pillar. The storage layer includes a plurality of first protruding portions at interfaces between the conductive layers and the dielectric layers.

Abstract: Disclosed is a space partitioning method for a database table, including: determining a first data amount within a first time period and a second data amount within a second time period of the database table; calling a target network model, inputting the first data amount and the second data amount into the target network model, and outputting a third data amount within the target time period, wherein the target network model is configured to predict a data amount of a next time period based on data amounts of a previous time period and a current time period; and determining a number of target regions based on the third data amount within the target time period, and partitioning, based on the number of target regions, a space in the database table configured to store the data to be stored.
