Smart card management method, memory storage device and memory control circuit unit

Abstract

The invention provides an intelligent card management method, a memory storage device and a memory control circuit unit. The method comprises the following steps: receiving a first setting instruction corresponding to a temporary file from a host system, wherein the temporary file is used for storing an intelligent card and the first setting instruction comprises a plurality of first setting information; one of the first setting information comprises first setting instruction verification information and first position recognition information; the first setting instruction verification information is used for verifying whether the first setting instruction is used for setting the temporary file or not; and the first position recognition information is used for finding out a logic unit which comprises the first position recognition information and corresponds to first setting information. The method further comprises the step of recording a first logic range belonging to the temporary file to a lookup table according to the first setting instruction.

Description

technical field [0001] The present invention relates to a smart card management method, and in particular to a smart card management method, a memory storage device and a memory control circuit unit. Background technique [0002] As users gradually accept the use of electronic wallets and prepaid stored value, the use of smart cards is becoming more and more 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 a holder to perform predetermined operations. The smart card provides computing, encryption, two-way communication and security functions, making this card not only store data, but also protect the stored data. The Subscriber Identification Module (SIM) card used in the cellular phone using the Global System for Mobile Communications (GSM) mechanism is one of the application examples of the smart card. However, the smart card itself is l...

Problems solved by technology

However, the current data access method proposed by Google in the Android 4.4.2 version only allows the user's application to access data in a specific directory, so the user's application may not be able to access the data due to insufficient permissions. some temporary files for data writing

On the other hand, although the above-mentioned problems can be avoided by dynamically creating temporary files in the host system, when the logical address (LA) of a certain dynamic temporary file is fragmented or discontinuous, the memory device may not be complete. Record the logical address of this dynamic temporary file
