Flash storage technology status and development research

Abstract

Abstract Data storage devices are an important component of computer systems. Solid-state Drives, which use NAND Flash technology, are widely used in various fields due to their unique advantages such as high read-write speed, low power consumption, shock resistance, and small size compared to traditional mechanical hard drives. This paper first discusses the basic structure and principles of Flash memory, including floating gate transistors for storing and reading charges. Based on the current state of NAND Flash-based solid-state hard drives, this paper discusses key technologies and characteristics such as flash memory types, wear leveling, garbage collection, etc. It explores their features, advantages and limitations, and finally reasonably deduces the future development trend of Flash devices.
