Method and system for storage device management and memory storage device of same

Abstract

The invention provides a method and system for storage device management and a memory storage device of the same. The method comprises the step that multiple first temporary files are established in a first data folder before a setting instruction is received from a host, wherein the first temporary files are stored in multiple continuous clusters of a file system, and an operation system of the host cannot get access to the files in the first data folder. The method also comprises the step that the setting instruction is received from the host, wherein the setting instructions indicate that temporary file data can be configured in a second data folder, and the operation system of the host can get access to the files in the second data folder. The method also comprises the steps that cluster numbers of the continuous clusters which store the first temperature files in a catalog zone of the corresponding file system are gathered to a temperature file data folder. The method and system for the storage device management and the memory storage device of the same provided by the invention have the advantages that logic addresses of the temporary files can be accessed correctly; and thus a smart card chip can be accessed.

Description

technical field [0001] The present invention relates to a storage device management method, and in particular to a storage device management method and system for a memory storage device configured with a rewritable non-volatile memory module and a smart card chip and its memory storage device. 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 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...

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 (logical address, referred to as: LA) of a certain dynamic temporary file is fragmented or discontinuous, the memory device may not be able to Completely record the logical address of this dynamic temporary file, or when the read and write actions span multiple logical addresses, the problem of accessing data is incorrect
