Problems solved by technology

Therefore, people hope that the operation of the flash memory storage device can also be partitioned like a hard disk, and attributes can be set for each area to facilitate the setting of different access rights for the stored data. Obviously, the flash memory storage device in the current technology is still cannot meet this need

Embodiment Construction

[0023] Such as figure 1 As shown, a flash storage device supporting partitioning has the appearance characteristics and interface signal definition of a common flash storage device, including an interface unit A, a controller B and a storage module C.

[0024] One end of the interface unit A is used to connect to the external host, and the other end is connected to the controller B. The interface unit A usually uses an interface connector or golden finger. Its interface signal definition can conform to different specifications according to different applications. If it is an SD memory card, it is an interface unit that conforms to the SD specification; if it is an MMC memory card, it is an interface unit that conforms to the MMC specification; if it is a USB storage device , it is an interface unit conforming to the USB specification, and so on.

[0025] Controller B and storage module C are connected through a bus. Together, controller B and interface unit A not only complet...

Abstract

This invention discloses a kind of flash saving device supporting the partition. It includes a interface unit, a controller and a memory module. One end of the interface unit connects with the host computer, the other with the controller. The controller and the memory module are connected by the concentration line. The controller can divide the total memory area of the memory module into several separate ones. Each separate memory area can read, write, erase, encrypt or set attribute separately. According to this invention, people can divide the memory area of the flash saving device into several areas of different size and set different attribute for every area. They can't affect each other.

Description

technical field [0001] The invention relates to storage technology, in particular to a flash memory storage device supporting partitions. Background technique [0002] Flash storage devices use flash memory devices as storage media and have various data communication interfaces, such as common flash memory cards with SD / MMC / MS interfaces, U disks with USB interfaces, etc. These flash storage devices are widely used in various digital storage devices such as digital cameras, PDAs, and MP3 players because of their small size, large capacity, and good shock resistance. [0003] Generally, a flash memory device includes an interface unit, a controller, and a memory module. [0004] The interface unit is connected to the host computer, generally an interface connector, whose interface signal definition can conform to different specifications according to different applications, and can be SD, MMC, USB, etc. Together, the controller and the interface unit complete data transmiss...
