A flash storage comprises a flash memory, including a plurality of physical memory blocks, each of physical memory blocks comprising a plurality of memory segments, and a plurality of physical sectors, and each of physical sectors being further provided therein with at least a user data column and a logical address pointer column. When physical data is written into the user data column, writing logical address pointer data into the logical address pointer column of the same physical sector may be performed together by the control of a micro-controller. Furthermore, the logical address pointer data in the same memory segment are arranged to be a backup memory segment address mapping table and then stored in one physical memory block. The backup memory segment address mapping table may be loaded directly and stored into a registered memory by the micro-controller when the system boots. Thus, not only shortening the startup duration of the flash storage, but also saving the memory capacity of the registered memory and securing data access may be obtained.

Flash storage system with data storage security

A memory card with multiple interface functions is provided. The memory card comprises a multiple interface controller, comprising at least a USB processor, MMC/HS MMC processor and SD processor, and each processor individually connected to a data r/w controller and a shared interface bus, the data r/w controller connected to at least a data-storage medium, and shared interface bus connected to a computer system or IA product. The function of a mode detector/switch is used for detecting the compatible transmitting mode of the connected computer system or IA products, and to switch shared interface bus to match USB processor, MMC/HS MMC processor or SD processor for application. Thus, selecting transmitting mode between data r/w controller and the computer system or IA products connected thereto, the present invention does not only economize on the usage of card reader but also could be applied to various transmitting interface devices and enhancing on its user-friendly performance.

Method for determining transmitting mode of a memory card with multiple interface functions

An improved structure of USB compatible application apparatus is mainly provided a PCB circuit board to be a USB compatible application module of a connector. A top surface of the PCB carrying board is used to carry a plurality of connecting terminators. A board bottom sandwich is naturally formed between a bottom surface of the PCB carrying board and an covering shell of the connector. At least one electrical element are fixed inside of the board bottom thereby selectively reducing a length of a USB compatible application module or increasing working efficiency of the USB compatible application module. Further, at least one board top data transmission lines are set on part of the top surface of the PCB carrying board without setting the first connecting terminators thereby further raising working efficiency of the USB compatible application apparatus.
