Embodiment Construction

[0013] The above and other technical features and advantages of the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0014] figure 1 is a schematic diagram of an embodiment of the flash memory device of the present invention. Such as figure 1 As shown, the flash memory device 10 is coupled to a host 13 and includes a flash memory 11 and a controller 12 . The flash memory 11 is pre-formatted with a default file system, such as but not limited to FAT32. The flash memory 11 includes a user area 111 and a system area 112, wherein the user area 111 is the area used by the user to access the flash memory device 10 through the host computer 13, and the system area 112 stores the data required for the operation of the controller 12. software and related information. In this embodiment, the user area 111 stores a default file, and the system area 112 stores a default logical address.

[0015] After the host 13 opens the defa...

Abstract

The present invention provides a flash memory device and a control method thereof, which has the specific function of utilizing a simple and special design to start the flash memory device. The flashmemory device is coupled with a host and includes a controller coupled with a flash memory. The flash memory includes a user area and a system area; the user area stores a preset file and the system area stores a preset logical address. The host sends out a write-in command after starting up the preset file in a write-in mode and the write-in command is corresponding to a write-in logical addressand includes a first information. If the controller judges the write-in logical address is the preset logical address and the first information is corresponding to the preset function in the flash memory device, the controller starts up the preset function.

Description

technical field [0001] The invention relates to a flash memory device, in particular to a flash memory device capable of activating a specific function in a special way and a control method thereof. Background technique [0002] In recent years, flash memory has become the memory medium used by most portable memory devices. Such as USB flash disk (USB Flash Disk, commonly known as silicon disk drive or thumb brother), and including small size flash memory (Compact Flash, CF), memory stick (Memory Stick, MS), secure digital (Secure Digital, SD), multimedia card (Multi Media Card, MMC) and other specifications of flash memory card (flash memory card), using CF or USB interface micro hard disk (micro hard disk), or using USB or PCMCIA interface and installed in an external box Thin 2.5-inch hard drives, etc., to meet the modern people's desire for "information portability" and increasing day by day. In addition, in many portable electronic devices using embedded memory, such ...
