1. A response reading method, adapted for data transmission between a system and a memory storage device, wherein the system has a cache memory, and the memory storage device has a smart card and a rewritable non-volatile memory module, the response reading method comprising: transmitting a first operation command sequence corresponding to a first temporary file to the memory storage device by the system, wherein the first operation command sequence is configured to instruct the smart card to execute a first operation; executing a first writing operation corresponding to a first dummy file by the system, wherein the first writing operation is configured to update first data in the cache memory; and executing a response reading operation corresponding to a second temporary file by the system, wherein the response reading operation is configured to read a response of the smart card corresponding to the first operation command sequence.
