NAND flash, as the mainstream storage medium, has the advantages of high performance, high density, non-volatile and low power consumption. However, due to the special internal structure of NAND flash, it is necessary to design a special controller for data management, which is suitable for all kinds of storage systems. In this paper, a NAND flash controller based on NB-LDPC is completed. We will describe the construction of LDPC code, the implementation of encoding circuit, the realization of d...
