HeterMM: Applying in-DRAM index to heterogeneous memory-based key-value stores

"byte-addressable non-volatile memory = cost-effective/ larger-capacity... dynamic random-access memory = superior performance... heterogeneous memory architecture consisting of both... plugged-in in-DRAM index, operation log for failure recovery... newly written data resides in DRAM, each piece old data flushed to NVM in batches allocated logical address upon arrival, remaining same unless updated out-of-place... holds hot data in NVM allowing read requests to be served by DRAM without accessing NVM"
