Abstract
An apparatus includes a non-volatile memory and a controller coupled to the non-volatile memory. The controller includes a volatile memory configured to store a first copy of a control table associated with the non-volatile memory. The controller is configured to perform a first update of a portion of the first copy of the control table in response to a first request, to initiate a second update of a second copy of the control table at the non-volatile memory based on the first update, and to execute a second request for access to the non-volatile memory concurrently with of the second update. The controller is configured to perform non-blocking control sync operations and non-blocking consolidation operations asynchronously, wherein non-blocking consolidation operations are atomic operations that include concurrent evacuation and compaction of an update layer to a cached address translation table in the volatile memory.
