Abstract
A method to perform atomic transactions in non-volatile memory (NVM) under hardware transactional memory is disclosed. The method includes tracking an order among transaction log entries that includes arranging transaction logs in an order that is based on when corresponding transactions were executed. Moreover, the method includes, using the ordered transaction logs to recover data states of the nonvolatile memory, by identifying a first unconfirmed transaction associated with a transaction completion uncertainty event based on a corresponding one of the transaction logs including a first commit marker but not including a confirm marker, undoing first ones of the transactions in reverse time order starting at a last transaction that recorded a second commit marker, up to and including the first unconfirmed transaction that recorded the first commit marker, and redoing second ones of the transactions in forward time order from a first confirmed transaction up to but not including the first unconfirmed transaction that recorded the first commit marker.
