A plurality of generators that each correspond to a respective one of a plurality of cursors associated with the plurality of memory devices are identified. A sequence of logical unit numbers (LUNs) of a plurality of sequences of LUNs are generated for each of the cursors based on a respective generator corresponding to the plurality of cursors. Each of the cursors are directed to perform a memory operation on a set of LUNs in an order provided by the sequence of LUNs that is associated with each of the plurality of cursors.
