Tracking persistent memory usage
Disclosed herein are techniques for tracking usage of a storage-class memory. In one embodiment, a method includes receiving a first statistics update entry and a second statistics update entry by a memory controller for a memory, and assembling the statistics update entries into a statistics log entry. The first statistics update entry indicates a number of operations performed on a first memory block in the memory, and the second statistics update entry indicates a number of operations performed on a second memory block in the memory. The method also includes determining a persistent memory region in a persistent memory for storing the statistics log entry, and writing the statistics log entry into the persistent memory region, where the statistics log entry persists in the persistent memory region until the statistics log entry is read back through the memory controller.
