Seungjae Baek, Sangyeun Cho, Jongmoo Choi, Francesco Pappalardo
2017 PLoS ONE  
Solid-state drives (SSDs) have recently become a common storage component in computer systems, and they are fueled by continued bit cost reductions achieved with smaller feature sizes and multiple-level  ...  Our scheme is motivated by the observation that frequently written hot data will eventually enter the cache with a high probability, and that infrequently accessed cold data will not enter the cache easily  ...  Jung et al. propose a new hot/cold identification scheme that uses process identification (PID) as a hot/cold indicator [8] .  ...

CFTL

Dongchul Park, Biplob Debnath, David Du
2010 Proceedings of the ACM SIGMETRICS international conference on Measurement and modeling of computer systems - SIGMETRICS '10  
Unlike other existing FTLs using static address mapping schemes, CFTL is adaptive to data access patterns so that it can dynamically switch its mapping scheme to either a read-optimized or a write-optimized  ...  Since FTL has a critical impact on the performance of NAND flash-based devices, a variety of FTL schemes have been proposed to improve their performance.  ...  That is, we maintain a counter for every logical page address, instead of adopting bloom filter, to reduce false identification. • Addressing Mode Switches: If a hot/cold data classifier in CFTL identifies  ...
