Design and implementation of a NAND Flash controller in SoC

摘要

NAND Flash is widely used in modern digital products and it has become a trend to integrate NAND Flash controller into SoC. This paper discussed the implementation scheme of the NAND Flash controller in detial, including the design of state machine, ECC module and so on. In order to improve the data access speed of NAND Flash Controller, this paper proposed two technologies which increase little area but improve the performance of the controller effectively. The test results based on FPGA showed that this design had high practical value. Based on SMIC 0.18µm standard CMOS technology, this design can work at the frequency of 121MHz.
