Description

Slot card modules with high security

technical field

The invention relates to a slot card insertion structure, in particular to a high security slot card insertion module with various auxiliary safety and convenience functions.

Background technique

With the development of thin and small flash memory technology, it has been widely used as a storage device for various information products. For example, digital cameras, recording pens, music players, etc. all use flash memory as their main storage. Media, especially CF Card (Compact Flash Card) card or more functional CFast card, etc., because of its high compatibility, fast access speed, large capacity, extremely low power consumption, small size, and dustproof , shock resistance, drop resistance and other advantages, so it is widely used in various information products, and can even replace the traditional IDE interface hard disk as the system hard disk of the computer host.

The composition and application technology of existing CF module (plug-in card module) are as shown in Figure 1, and it comprises a CF slot 94, and this CF slot 94 is arranged on a mainboard 90, in order to insert for a CF card 95 If used, the motherboard 90 is also provided with a CPU socket 91 (for plugging in the CPU), an expansion slot 92 (such as a CPI bus bar, etc.) and related electronic components and circuits such as a chip 93 . Although this existing CF module can achieve a high-speed, high-stable transmission interface as a general data access, it has not given full play to its proper auxiliary functions relative to the mainboard, such as expanding the information transmission used in other functional modules. room for enhancement and improvement.

Furthermore, in today's industrial computer market, the BIOS is stored in a non-fault-tolerant SPIFlash (Serial Peripheral Interface/Serial Peripheral Interface) Rom on the motherboard. This architecture does not have the mutual backup of the second BIOS, so There is no way to implement fault-tolerant applications. For example, if the motherboard of the client fails to boot (or access the Internet), the basic judgment can be whether the BIOS CODE is damaged. However, the existing motherboard does not have fault-tolerant auxiliary detection. As a result, it is impossible to quickly clarify whether this is the reason, so that the client can only pull out the SPI Flash IC, and then take it to a machine dedicated to burning the IC and re-burn the correct BIOS CODE to make a judgment, but not every time Every customer can carry out this inspection operation, or not every server will have a related burning machine, and it will take more time to solve the problem in terms of timeliness, and it will also affect the normal use of the computer system of the client, which is obviously very serious. ideal design. Therefore, how to improve the deficiencies in the operation of the existing motherboard should be an important direction for the industry or wise people to solve and overcome.
