Embodiment Construction

[0050] Generally speaking, a memory storage device (also known as a memory storage system) includes a rewritable nonvolatile memory module and a controller (also known as a control circuit). Generally, the memory storage device is used with the host system so that the host system can write data to the memory storage device or read data from the memory storage device.

[0051] Figure 1A It is a schematic diagram of a host system using a memory storage device according to an exemplary embodiment of the present invention.

[0052] The host system 1000 includes a computer 1100 and an input / output (Input / Output, I / O) device 1106. The computer 1100 includes a microprocessor 1102, a random access memory (Random Access Memory, RAM) 1104, a system bus 1108, and a data transmission interface 1115. The microprocessor 1102 executes the operating system 1110 and the application program 1120 installed in the random access memory 1104, so that the host system 1000 provides corresponding function...

Abstract

The invention relates to a data processing method, a memory controller and a memory storage device. The method comprises receiving a write instruction from a host system, wherein write data corresponding to the write instruction comprise a plurality of subdata, each subdata is installed at an application program of the host system and a data index marker is added individually, and the application program determines the data index markers added to the each subdata according to a preset function, an initial parameter value selection mode and a parameter value newly increased mode included in a first rule concerted with the memory storage device in advance. The method also comprises reordering all subdata according to the first rule concerted with the application program in advance and the data index markers of the subdata. The method also comprises transmitting the reordered subdata to a smart card chip.

Description

Technical field [0001] The present invention relates to a data processing method, and more particularly to a data processing method for a memory storage device having a rewritable non-volatile memory module and a smart card chip, and a memory storage device using this method And memory controller. Background technique [0002] As users gradually accept the use of electronic wallets and prepaid stored value, the use of smart cards has become increasingly popular. A smart card (Smart Card) is an integrated circuit chip (IC chip) having components such as a microprocessor, a card operating system, a security module, and a memory to allow the holder to perform predetermined operations. The smart card provides computing, encryption, two-way communication and security functions, so that in addition to the function of storing data, the card can also achieve the function of protecting the stored data. The Subscriber Identification Module (SIM) card used in cellular phones using the Glo...
