The Design of NAND Flash Controller Supporting ONFI
-
Abstract
A Solid State Drivers' controller supporting ONFI standards based on NAND Flash was designed. The soft-core MicroBlaze was played as the controller processer. And AXI bus was used to transmit data efficiently. Under the control of pointer controller module, ping-pang structure was realized to increase throughput rate. Logic optimization of the main module made writing operations much more efficient. Results showed that all sequence diagrams met ONFI standards strictly.
