Abstract

A silicon disk card with a USB plug includes an electric circuit board with at least one flash memory and a bridging chip, and a module in the shape of a rectangular frame formed by injection molding of plastic. The module is provided on one side thereof with an interface pin board, and on the opposite side thereof with a slot to receive the USB plug therein, the slot having a leading function to lead the USB plug out of the module. The silicon disk card with the USB plug has the function of twin interface data transmitting, the bridging chip being used therein to decide which interface is seeking access to data in the flash memories.

Claims

1. A silicon disk card with a USB plug comprising:

an electric circuit board faith at least one flash memory and a bridging chip;

a module including a rectangular plastic frame, said module being provided on one side thereof with an interface pin board electrically connected to said circuit board, and on the opposite side thereof with a slot to receive said USB plug therein, said USB plug also being electrically connected to said circuit board,

wherein said silicon disk card forms a twin interface data transmission means for enabling access to said flash memory by both a USB interface and said interface pin board, said bridging chip provides a means for discriminating which interface is accessing said data, and said slot forms a means for guiding said USB plug out of said module when in use in order to connect said plug to an external USB device.

2. A silicon disk card with a USB plug as claimed in claim 1, wherein said USB plug is connected to said circuit board by a transmission line.

3. A silicon disk card with a USB plug as claimed in claim 1, wherein said USB plug is connected to said circuit board by a fixed point connection.

4. The silicon disk card with a USB plug as in claim 1, wherein said module includes a top plate and a bottom plate, said circuit board, said interface pin board, and said USB plug being mounted between said top plate and said bottom plate, said top plate and said bottom plate being arranged to protect interior electronic elements from dust, wherein either of said top and bottom plates forms said slot.

5. The silicon disk card with a USB plug as in claim 1, wherein said silicon disk card is a PCMCIA card and said interface pin board has 68 pins.

6. The silicon disk card with a USB plug as in claim 1, wherein said silicon disk card is a Compact Flash type I/II card and said interlace pin board has 50 pins.

7. The silicon disk card with a USB plug as in claim 4, wherein said USB plug is fixed on electric circuit board by an axle, so that said USB plug is adapted to rotate about said axle to a position in which the USB plug extends out of said slot during use, and said USB plug is adapted to be received in said slot when not in use.

8. The silicon disk card with a USB plug as in claim 4, wherein said USB slot is fixed on two parallel framing sides located laterally of said slot by al axle, so that said USB plug is adapted to rotate in a vertical plane about said axle to a position in which the USB plug extends out of said slot during use, and said USB plug is adapted to be received in said slot when not in use.

9. A silicon disk card with a USB socket comprising:

an electric circuit board with at least one flash memory and a bridging chip;

a module in the shape of a rectangular frame formed by injection molding of plastic, said module being provided on one side thereof with an interface pin board; and

a small USB socket provided in any one of the four sides of said rectangular frame to enable connection of a USB plug,

wherein said silicon disk card forms a twin interface data transmission means for enabling access to said flash memory by both a USB interface and said interface pin board, said bridging chip provides a means for discriminating which interface is accessing said data.
