Zusammenfassung:Systems, methods, and/or devices are used to manage high-priority NAND operations. In some embodiments, the method includes receiving a first command (e.g., requesting a high-priority memory operation) corresponding to a first location (e.g., having both a first physical address and a first aliased physical address) in a first die of a plurality of physical non-volatile memory die in a storage device. If the first die is performing a blocking low-priority memory operation (e.g., the low-priority operation was sent to the first die using a second physical address), the method includes sending a memory operation command, corresponding to the first memory operation, to the first die using the first aliased physical address. In some embodiments, a predefined die-selection portion of the second physical address matches the predefined die-selection portion of the first physical address and does not match the predefined die-selection portion of the first aliased physical address.
