Abstract
A controller of the data storage system may poll a non-volatile memory component to determine an operational status of the non-volatile memory component after a memory operation has been initiated in the non-volatile memory component. The controller may, in response to determining the operational status of the non-volatile memory component is busy, update a polling interval based on a polling factor. The controller may re-poll the non-volatile memory component to determine the operational status of the non-volatile memory component after expiration of the updated polling interval. The controller may repeat the updating of the polling interval and the re-polling of the non-volatile memory component until the operational status of the non-volatile memory component is determined to be ready or until a predetermined number of iterations of the updating and re-polling have been performed if, in response to the re-polling, the operational status is determined to be busy.
