Data storage device and operation instruction scheduling method thereof

Abstract

A data storage device and an operation instruction scheduling method thereof are provided, wherein the data storage device includes a controller and a non-volatile memory, the controller includes a register. The register includes a power consumption index list. The non-volatile memory is used to store a plurality of instructions. The controller is used to execute the plurality of instructions to implement the operation instruction scheduling method which comprises: determining that a first operation instruction to be executed is a power-consuming operation instruction; determining that a first column of a first part of the power consumption index list stores the first operation instruction so as to enable a first valid bit corresponding to the first column; executing the first operation instruction on the non-volatile memory based on the first valid bit; and clearing the first column and the first valid bit when an operation instruction completion signal of the first operation instruction is received.
