Data processing method, memory controller and memory storage apparatus

A memory controller, configured in a memory storage apparatus having a rewritable non-volatile memory module and a smartcard chip, the memory controller comprising:

• a host interface, configured to couple to a host system;
• a memory interface, configured to couple to the rewritable non-volatile memory module, wherein the rewritable non-volatile memory module has a plurality of physical erase units, and each of the physical erase units has a plurality of physical program units;
• and
• a memory management circuit, coupled to the host interface and the memory interface and receive a write command from the host system,
• wherein a write data stream corresponding to the write command comprises a plurality of sub-data streams, and each of the sub-data streams is attached with a data index mark by an application installed in the host system,
• wherein the write data stream corresponds to an original data stream to be transmitted to the memory storage apparatus by the application, and a first rule is pre-agreed by the memory storage apparatus with the application, wherein the first rule comprises a predetermined function, an initial parameter selecting manner and a parameter increasing manner,
• wherein the application selects an initial parameter according to the initial parameter selecting manner, substitutes the initial parameter into the predetermined function so as to obtain the data index mark attached to a first sub-data stream in the original data stream and determines the data index mark individually attached to each of the other sub-data streams among the sub-data streams according to the parameter increasing manner, the data index mark of the first sub-data stream and a sequence of the sub-data streams in the original data stream,
• wherein the memory management circuit is further configured to reorder the sub-data streams according to the first rule pre-agreed with the application and the data index mark of each of the sub-data streams, and
• wherein the memory management circuit is further configured to transmit the reordered sub-data streams to the smartcard chip.
