WebNVM is mainly caused by the fact that CAS and other atomic hard-ware instructions do not persist their updates to NVM automatically and atomically. An update only modiﬁes the target word in the processor cache and does not automatically update the target word in NVM. In case of a power failure, the volatile cache content is lost http://nvmw.ucsd.edu/nvmw2024-program/nvmw2024-data/nvmw2024-paper17-final_version_your_extended_abstract.pdf
