SYSTEM AND METHOD OF ARBITRATION ASSOCIATED WITH A MULTI-THREADED SYSTEM

A data storage device includes a controller coupled to a non-volatile memory via a data path element. The controller includes a first queue that includes a first set of requests and a second queue that includes a second set of requests. The controller further includes logic configured to assign a particular request from the first queue or from the second queue to have access to the data path element. When the logic is in a first mode, the logic selects a particular request is selected based on an arbitration scheme applied to the first queue and the second queue. When the logic is in a second mode, the logic selects a prioritized request from the first set of requests or the second set of requests independently of the arbitration scheme.
