1. An identification method, used in an embedded equipment having a storage device having multiple storage dies, the embedded equipment comprising a processing unit and a synchronous dynamic random access memory device, the identification method comprising:
establishing a memory timing look-up table and storing the memory timing look-up table in the synchronous dynamic random access memory device;
establishing a dynamic random access memory type mapping table, and storing the dynamic random access memory type mapping table in the synchronous dynamic random access memory device;
utilizing the processing unit to check a number of universal input/output pins of the storage device having multiple storage dies;
utilizing the processing unit to preload and initiate voltage levels of the universal input/output pins;
utilizing the processing unit to obtain a composite voltage level information of the universal input/output pins and obtaining a dynamic random access memory type through the dynamic random access memory type mapping table;
utilizing the processing unit to obtain a memory timing number of a random access storage device through the memory timing look-up table according to the dynamic random access memory type; and
utilizing the processing unit to initialize the random access storage device according to the memory timing number to complete an identification operation.
