Deduplication in resistive content addressable memory based solid state drive

An in-storage deduplication based on a resistive content addressable memory (ReCAM) is proposed. The ReCAM native compare operation is used to find duplicate data blocks in a fixed number of cycles. The performance of ReCAM based in-storage deduplication is compared to Solid State Drive (SSD) based in-line deduplication performed in CPU and DRAM, showing an average 100× higher throughput at roughly the same energy consumption.
