Abstract: A processing device in a memory sub-system detects a preemptive power loss condition in the memory sub-system and, in response, causes operations of a local media controller associated with a memory device in the memory sub-system to be suspended, wherein responsive to being suspended, the local media controller to perform power loss handling operations to complete a subset of a plurality of pending memory access operations, and wherein to perform the power loss handling operations, the local media controller to complete the subset of the plurality of pending memory access operations for which an acknowledgment signal has been sent to a requestor. The processing device further detects a full power loss and restore condition in the memory sub-system, responsive to detecting the full power loss and restore condition, initializes the memory device and causes operations of the local media controller to resume.
