Title: Introduction to Advanced Flash Memory

Abstract:
As IoT, AI and 5G technologies are advanced, it is predicted that more than 170ZB (zettabyte) data will be generated by 2025, which is so-called “data explosion”. Storage is the key component to handle those big data. As conventional planer NAND flash memories are limited from physical and electrical scaling point of view, the three-dimensional NAND (3D-NAND) flash memories, in which memory cells are stacked vertically, has rapidly achieved maturity to keep a trend of increasing bit density and reducing bit cost. This lecture aims to understand this 3D flash memory technology, especially focusing on the structures and operation of memory cells.
