Scheduling of read operations and write operations based on a data bus mode
A data bus can be determined to be in a write mode based on a prior operation transmitted over the data bus being a write operation. In response to determining that the data bus is in the write mode, a number of partition queues of a plurality of partition queues that include at least one write operation can be identified. A determination as to whether the number of partition queues of the plurality of partition queues satisfies a threshold number can be made. In response to determining that the number of partition queues satisfies the threshold number, another write operation from the plurality of partition queues can be transmitted over the data bus.
