Abstract
The present disclosure generally relates to more effective utilization of write and read bandwidth in submission queues (SQs). The data storage device treats a SQ as two separate SQs: one write SQ and one read SQ. Rather than a single fetch pointer for the entire SQ, the write SQ has a write fetch pointer (WFP) while the read SQ has a separate read fetch pointer (RFP). So long as the individual pointers are less than a queue pointer (QP), the data storage device can still process commands for either read or write SQ even if the other SQ has run out of credits. In so doing, read and write bandwidths can be effectively utilized.
