Transactional memory provides high performance and ease of maintenance by dividing the instruction set of a program into transactional units. However, data is lost if system failure occurs. To solve this problem, a non-volatile memory-based transactional memory called NV-HTM has been proposed. NV-HTM is a hardware transactional memory (HTM) that supports data recovery on NVM(Non-Volatile Memory) even in the event of system failure. However, since NV-HTM uses SGL as a fallback path, it cannot support parallel processing for transactions which fail using hardware transactional memory. Thus, in this paper, we propose a NVM-based hybrid transactional memory (DHyTM) that provides data recovery on NVM and supports parallel processing between the fallback path and HTM path. It is shown from the performance evaluation that the proposed DHyTM has demonstrated an average performance improvement of 270% over NV-HTM in the STAMP benchmark.
