Abstract:

In the development of NAND type solid storage system,interface chip directly affects the performance of the storage system,and an independent design of NAND controller is needed in order to maximize the performance of reading and writing.The structure of interface characteristics of NAND Flash and NAND controller is analyzed,the main logic of NAND controller and the common programming commands are described using the state machine,and the state machine logic is realized by the use of FPGA.Simulation test on the NAND main operation command shows that the design meets the requirements of NAND Flash operation timing.

Key words: FPGA;state machine;NAND controller;interface
