Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention generally relates to a storage media, and more particularly relates to a memory card, a memory card connector and combination thereof.
2. Description of the Prior Art
Currently, many electronic consuming products have their own memory cards to perform the data access, but there are various types of memory cards in the market, for example, the SD memory card, the MMC memory card, the CF memory card, the MS memory card, the SM memory card, the XD memory card, the RS-MMC memory card, the mini-SD memory card, the Trans Flash memory card and other different memory cards. Therefore, the manufacturers produce many kinds of specifications of memory cards to adopt the consuming products. And, a user usually needs to purchase the additional memory cards for complying with the consuming electronic products. It is expensive and complicated to manufacture various specific memory cards for these electronic consuming products.
For solving the question hereinabove, many manufacturers design various memory card connectors, for example, a USB standard interface is applied in a USB card reader for conversion. FIG. 1 is a conventional memory card connector schematic diagram. A connector 10 has a space 12 on one end to position a memory card 14, and another end of the connector 10 has a USB portion 16 to connect with the electronic product that has the USB portion thereby. The connector 10 may be designed with different size of the space 12 configuration for different memory cards. However, a user still needs the USB portion 16 to perform the connecting operation. Therefore, the connector 10 cannot satisfy the user's requirement.
Next, FIG. 2 is another diagram illustrating an exemplary memory card connector of U.S. Pat. No. 7,152,801. As FIG. 2 shows, one end of a memory card 18 has a USB portion 20, wherein it is necessary for a user to utilize a connection-housing 22 to configure with the memory card 18 along the arrow A. However, a large size of the memory card 18 can not be converted to the small size of memory card by the connection-housing 22, for example, the CF memory card can not be converted to the XD memory card by the connection-housing 22 directly, and therefore causes the limitation in practical use.

Therefore, the user only needs to distinguish the specification of memory card from the specific electronic product, and choose the proper memory card connector having an appearance of the second memory card. Then, the first memory card and the memory card connector having an appearance of the second memory card are assembled as the memory device thereby. The memory device is configured in the specific electronic product to be utilized, for example, the user owns a digital camera (DC) and personal digital assistant (PDA) that have the specifications of memory card are XD and CF respectively. If the user utilizes the first memory card and the memory card connector having an appearance of the second memory card from the present invention, the first memory card is configured in the second memory card connector with an appearance of the XD memory card or the CF memory card. Therefore, the user achieves to covert the specifications of XD memory card and CF memory card to the DC and PDA each other for data sharing and storage.
To make a summary, the present invention provides the first memory card and the memory card connector having an appearance of the second memory card, the user only needs to follow the specifications of the memory card from the electronic product to embed with certain memory card connector thereby. After assembling, the memory device is replaced of the memory card to configure in the electronic product. Therefore, the memory device is converted as various kinds of memory cards without additional memory card connectors. Meanwhile, the first memory card is converted as the compatible interface with different specifications of the second memory card. Therefore, the user easily purchases the memory with lower price.
