Memory storage device with integrated memory card adapter interface

technical field

The utility model relates to a memory storage device of a computer, in particular to a memory storage device with an integrated memory card adapter interface.

Background technique

Press, the memory card is becoming an important medium for storing data in portable devices nowadays, devices such as digital cameras and portable digital audio players all use memory cards in a convenient and space-saving way Generally speaking, if you want to read the data stored on the memory card, such as digital images, the portable device must be connected to the host computer or use the dedicated converter of the individual memory card. If you connect the portable device to the host computer to read the data, you usually need to plug and unplug the device every time you need to access the data on the memory card, which is very inconvenient and time-consuming Yes, another method is to use its own adapter for the specific type of memory card used. However, since the types of memory cards used by different types of devices are not the same, if you need to It is not economical to purchase additional adapters for memory cards. In addition, when accessing data on individual types of memory cards, the adapters must be inserted and pulled out. Therefore, people need an improved system that allows users to There is no longer a need for a dedicated memory card reader for various types of memory cards.

Contents of the invention

In order to overcome the shortcomings of the traditional memory card reader, the utility model provides a memory storage device with an integrated memory card adapter interface, so that the host computer can read the memory card through the memory storage device data, or write data to the memory card.

However, there are more and more memory cards with different interfaces and connectors. Memory cards require a dedicated adapter, which restricts the high-speed data bus and makes it impossible to use it on other devices.

The memory storage device with an integrated memory card adapter interface of the present invention includes: a high-speed data bus for connecting the flash memory storage device and a host computer; a high-speed data bus for processing standard A controller and flash memory for scheduling commands and storing data; and a memory card adapter interface for connecting the memory card and the flash memory storage device.

The utility model provides a flash memory storage device, which is connected with a host computer through a high-speed data bus such as a universal serial bus (USB) or 1394 or firewire bus. In addition, the flash memory storage device Contains an integrated extension adapter that allows the memory card to be connected to a flash memory storage device and allows a host computer to communicate with the memory card using a high-speed data bus.

For example, a specific form of the present invention includes that the flash memory device is connected to a host computer using a Universal Serial Bus (USB) interface, and the host computer uses the Universal Serial Bus (USB) protocol to write data into the flash memory for storage. device and read data from the flash memory storage device. To the host computer, the flash memory storage device is a standard universal serial bus (USB) storage device, which means that the flash memory device can handle standard In addition, it can be connected to a memory card (such as a small flash memory card, etc.) through the adapter interface of the flash memory storage device, and the connection interface includes A mating connection suitable for the standard connector on the memory card, once the memory card is connected to the flash memory storage device, the host computer will automatically identify and verify the type and type of the memory card capacity, after the memory card is identified, the host computer can use the Universal Serial Bus (USB) interface provided by the flash memory storage device to read data from the memory card or write data to the memory card What has been described in this embodiment is a universal serial bus (USB) interface, yet, the high-speed data bus can be any high-speed data bus such as 1394 or firewire, in addition, although the memory in this embodiment The memory card is a compact flash memory card, but the memory card could also be a media memory card, microdrive, memory stick, mmc, secure digital, or other type of removable memory card.

When the memory card is connected to the flash memory storage device, and the host computer is also communicating with the flash memory storage device, the host computer will complete the current communication with the flash memory storage device before recognizing the memory card. There are orders.

It is hereby noted that the foregoing general description and the following detailed description are examples and are intended to further explain the present utility model.
