Abstract: Workload-dependent age tracking can improve quality of service in non-volatile memory (NVM). In one example, an NVM controller includes an age counter for each memory access command in a queue. Instead of incrementing the age counters every clock cycle (or other predetermined number of clock cycles), the age counters are adjusted (e.g., incremented) at an aging rate that is based on an average rate of scheduled commands for the queue. Thus, aging of commands in the queues speeds up or slows down depending on the workload. By aging commands at the rate of commands being scheduled, the scenario in which many commands become “starved” at the same time can be avoided, improving QoS and reducing errors.

Abstract: Systems and methods may provide for detecting a pending write operation directed to a target memory region and determining whether the target memory region satisfies a degradation condition in response to the pending write operation. Additionally, the target memory region may be automatically reconfigured as a cold storage region if the target memory region satisfies the degradation condition. In one example, determining whether the target memory region satisfies the degradation condition includes updating the number of write operations directed to the target memory region based on the pending write operation and comparing the number of write operations to an offset value, wherein the degradation condition is satisfied if the number of write operations exceeds the offset value.
