technical field

The present invention relates to a silicon disc card structure, and in particular to a multi-task silicon disc card structure, which can be connected to the USB interface system end platform due to its own structural design, and can also be a small Silicon disk card storage device.

Background technique

The development of the information product market has been towards products with small size, large capacity and multimedia functions, including: NB, computer peripherals, PDA, web-PAD, digital cameras, and digital video cameras. However, the demand for data storage capacity increases rapidly with the increase of functions. For the convenience and compatibility of data storage, there are currently a variety of products and specifications of small storage media on the market, including: Memory Stick card from Sony Corporation, There are many types of SecureDigital cards launched by Panasonic, as well as Compact Flash cards, Multi-Media cards, Smart Media cards, etc. These silicon disk cards are all made of silicon semiconductor storage technology (Semiconductor Storage), hereinafter referred to as rewritable memory/flash memory (FlashMemory), which not only has a small size, but also consumes Power, data retention, data transfer rate, repeatability, shock resistance, and moisture resistance are all far superior to conventional optical disc or magnetic disk technology.

On the other hand, the USB (Universal Serial Bus) standard version published in 1996 is a cross-platform expansion interface applied to computer systems or portable devices. USB has many advantages such as high transmission rate, hot swapping (Hot Swapping), plug & play (Plug & Play), and easy installation. or Notebook), computer peripheral products (such as scanners, keyboards, printers, mice, etc.), information appliances (IA) (such as personal digital assistants PDA), digital cameras (DSC), digital players (MP3 Player), Big Brother (also known as "Removable HardDisk"), etc., have been favored by consumers because of their convenience. Since USB and various silicon disks are used in products in various fields, and the interaction with consumers is becoming more and more frequent, in order to strengthen the transmission and circulation of data between silicon disks and various USB system end platforms, various Silicon disc reading devices (that is, card readers, silicon disc drives, or adapters) have emerged accordingly, such as: external silicon disc drives, built-in silicon disc drives, and silicon disc adapters, etc. product.

Although consumers can access data by purchasing suitable silicon disk reading devices for various specifications of silicon disk cards on the market, consumers will inevitably face considerable difficulties in choosing digital products in the future. Amplitude limitation. For example, if consumers find that people around them do not use MS cards or it is difficult to buy MS cards, they may think twice about purchasing a SONY digital camera that uses an MS card; on the contrary, for a Sony digital camera that has already purchased For consumers, if they want to buy a PDA next time, unless they want to use another silicon disk with different specifications, they may have to abandon other brands of silicon disk cards and choose SONY PDAs instead. Due to the variety of silicon disk cards with different specifications, consumers are subject to two important restrictions on products and prices, and this also explains why various manufacturers are willing to spend huge sums of money to participate in this silicon disk card specification war, making it The market promotion of silicon disc cards led by the company is of great help.

What's more, the launch of "Big Moo" has attracted the attention of consumers. It not only combines the above-mentioned rewritable memory with high storage capacity and repeatable memory characteristics, but also has a standard USB specification, which can be directly connected to a computer or Others have the plug-and-play function of the USB interface, and it is easy to directly transmit and exchange data with other types of consumer electronics products and digital communication devices. In a narrower view, Big Mog is a small portable hard disk, which provides the convenience of data storage and modification, and can be immediately connected to a desktop computer, notebook computer or handheld computer that has a USB system port interface and supports its settings. Exchange of data formats between computers, such as: MP3, VIDEO, PHOTO and other digital information.

However, at present, all kinds of small silicon disk cards of different specifications need to use a medium reading device (as mentioned above: external silicon disk drive, built-in silicon disk drive, silicon disk adapter and other products) , in order to connect with a computer or other devices with a USB interface; and although Big Brother can be directly connected to the USB system end, it cannot be applied to digital products such as general information appliances, digital cameras, and PDAs because it is difficult to build a USB interface. All silicon disk card interface devices. In other words, both devices (Silicon Disk or Big Mob) can be directly or indirectly connected to the USB system side, but they cannot be used with each other. As a result, the purchase cost of the consumer will be increased, causing inconvenience to the consumer in use.
