Abstract: The present invention discloses an operation instruction scheduling method and device for a NAND flash memory device. The method comprises: performing task decomposition on the operation instruction of the NAND flash memory device, and sending an obtained task to a corresponding task queue; sending a current task to a corresponding arbitration queue according to a task type of the current task in the task queue; and scheduling a NAND interface for a to-be-executed task in the arbitration queue according to priority information of the arbitration queue. Embodiments of the present invention can efficiently realize operation instruction scheduling of a NAND flash memory device, improve flexibility of operation instruction scheduling of the NAND flash memory device, and improve overall performance of the NAND flash memory device.
