Embodiment Construction

[0087] The invention provides a method for transmitting and identifying data strings, a memory storage device and a memory controller to manage data transmission between a host system and a memory storage device with a smart card chip. The data string can be sent from the host system to the smart card chip through the write command. Generally speaking, a memory storage device (also called a memory storage system) includes a rewritable non-volatile memory module and a memory controller (also called a control circuit). Typically memory storage devices are used with a host system so that the host system can write data to or read data from the memory storage device. Wherein, it is worth noting that the host system can be a mobile phone, a personal digital assistant (Personal Digital Assistant, PDA), a personal computer or other electronic products with cache memory.

[0088] The host system receives the response information generated by the smart card chip without error by execut...

Abstract

Disclosed are a memorizer storage device, a memorizer controller, and a data string transmission and identification method. The memorizer controller enables at least one part of data strings which are transmitted by a host system to be transmitted to an intelligent card chip of the memorizer storage device. Afterwards, by executing a plurality of reading commands, the host system can receive response information which is generated by the intelligent card chip inerrably. The memorizer controller can enable a first verification code to be added to and transmitted back to response data strings of the host system, and also can enable write-in tokens to be respectively recorded to each data zone section of response data strings. The host system confirms correctness of the response data strings through the first verification code or the write-in tokens of each data zone section.

Description

technical field [0001] The invention relates to a method for transmitting and identifying data strings, a memory storage device and a memory controller, in particular to a method for managing data string transmission between a host system and a memory storage device, a memory storage device and a memory controller. Background technique [0002] Digital cameras, mobile phones, and MP3 players have grown rapidly in recent years, making consumers' demand for storage media also increase rapidly. Because rewritable non-volatile memory (rewritable non-volatile memory) has the characteristics of data non-volatility, power saving, small size, no mechanical structure, fast read and write speed, etc., it is most suitable for portable electronic products, such as notebook computer. A solid state drive is a storage device that uses flash memory as a storage medium. Therefore, the flash memory industry has become a very popular part of the electronics industry in recent years.
