A first device may issue to a second device a first sequence of write commands for a set of data. The first sequence of write commands may indicate different memory addresses in an order. After issuing the first sequence of write commands, the first device may issue to the second device a second sequence of read commands for the set of data. The second sequence of read commands may indicate the different memory addresses in the same order as the first sequence of write commands. Based on issuing the second sequence of read commands, the first device may receive the set of data from the second device. ## Claims ### Claim 1 A method at a first device, comprising: issuing, to a second device, a first sequence of write commands for writing a set of data by the second device, the first sequence of write commands indicating different memory addresses in an order;
