NAND flash memory does not support the overwrite operation and thus it deploys the flash translation layer which performs the out-place update. When designing a flash translation layer, memory consumption, computation complexity, and garbage collection overhead should be low. However, the representative sector mapping scheme of flash translation layer, FAST causes a huge computation complexity even though it minimizes the memory consumption and the garbage collection overhead. This paper presents a hashed page table for the FAST scheme to reduce the computation overhead. The simulation result shows that the presented method contributes to reduce the computation overhead considerably.
