Patent attributes
A data storage device includes a memory device and a controller coupled to the memory device. The controller is configured to receive a plurality of fetch requests, determine a first number of requests, second number of requests, and a third number of requests of the plurality of fetch requests, and balance an execution of the first number of requests, the second number of requests, and the third number of requests so that a first ratio of the data requests to the PRP requests and a second ratio of the data requests to the HMB requests is about 1. The plurality of fetch requests includes PRP requests, HMB requests, and data requests. The first number of requests corresponds to a number of the PRP requests. The second number of requests corresponds to a number of the HMB requests. The third number of requests corresponds to a number of the data requests.
