An Efficient NAND Flash Garbage Collection Algorithm Based on Area and Block Operation
Garbage collection as a key technology for solid-state storage (SSD), it's has critical influence for the SSD's performance. This article addressed the low efficiency, high cost problem of the presented Garbage Collection (GC) Algorithm, Proposed a new Efficient NAND Flash GC Algorithm Based on Area and Block (GCbAB) Operation. The algorithm is not only efficient, low cost, but took into account the Wear Leveling, greatly improving the performance of SSD, extending the life of SSD. Through the actual verification, this algorithm is effective, and compared to existing algorithms have a great improved.
