Abstract: Example methods, systems, and apparatus to dynamically select between memory error detection and memory error correction are disclosed herein. An example system includes a buffer, to store a flag settable to a first value to indicate that a memory page is to store error protection information to detect but not correct errors in the memory page. The flag is settable to a second value to indicate that the error protection information is to detect and correct errors for the memory page. The example system includes a memory controller to receive a request based on the flag to enable error detection without correction for the memory page when the flag is set to the first value, and to enable error detection and correction for the memory page when the flag is set to the second value.

Abstract: A transactional memory system uses a volatile memory as primary storage for transactions. Data is selectively stored in a non-volatile memory to impart durability to the transactional memory system to allow the transactional memory system to be restored to a consistent state in the event of data loss to the volatile memory.
