A new multi-channel flash storage architecture based on intra-channel interleaving and inter-channel pipelining method was introduced.The theory of the multi-channel architecture was stated and the bottleneck of the throughput of NADN flash storage system was analyzed.Then,the bandwidth formula and speed-up ratio formula under the proposed two-level parallel method were derived.The reason of affecting the speed up rate was analyzed.In the end,the diagram of the multi-channel flash storage module based on pr...
