Hardware Transactional Memory (HTM)

Hardware Transactional Memory (HTM) is a technology that allows multiple processes or threads to access and modify shared data concurrently, similar to how transactions work in databases. HTM enables these operations to execute as a single, atomic unit—either all changes are committed if there are no conflicts, or none are applied if conflicts occur. This helps improve performance and simplify programming by reducing the need for complex lock management, allowing more efficient and safer parallel processing in modern CPUs.
