A Survey on Flash Translation Layer for NAND Flash Memory


The requirement for storage performance and capacity are increasing rapidly. NAND flash-based SSDs have been proposed as a reliable and speedy and low power consumption storage device. An important part of each SSDs is its flash translation layers (FTL). Flash translation layer is highly impact overall performance and it manages the internal data layout for storage. There are many different trade-offs involved in FTL implementation. This survey focuses on address translation technologies and provides a broad overview of existing schemes. In flash memory, flash translation layer is a very important structure and so many techniques have been proposed.
