Abstract

A removable memory card interface apparatus enables a removable memory card to communicate with a number of peripheral devices directly without the need for the memory card'"'"'s host or a host computer. The interface apparatus includes a micro-controller operating with an internal bus to control, process and route signals between the removable memory and a peripheral device via a series of memory and device interfaces. A control panel and/or remote control allows a user to interact with the interface apparatus. In one embodiment, the interface apparatus also allows a host computer to communicate with the memory card via one of the peripheral device ports. In other embodiments, the interface apparatus serves as a memory card printer controller or as a memory card player and/or recorder when interfaced with consumer electronics.

Claims

1. A memory card interface apparatus comprising:

an internal bus;

an external memory connector for removably coupling to a memory card;

a memory port connected to said external memory connector and coupled to said internal bus;

a plurality of external device connectors, each for coupling to a device that operates with said memory card;

a device port connected to each external memory connector and coupled to said internal bus;

a control panel coupled to said internal bus for specifying an operation mode of the interface apparatus;

a interface controller coupled to said internal bus and responsive to said control panel for enabling communication between said memory card and one or more devices coupled to said plurality of external device connectors.

2. A memory card interface apparatus as in 1, further comprising a parallel port coupled to said internal bus and to one of said plurality of external connectors, thereby supporting communication through a parallel port connection between said memory card and a peripheral device.

3. A memory card interface apparatus as in 1, further comprising a Universal Serial Bus interface coupled to said internal bus and to one of said plurality of external connectors, thereby supporting communication through an Universal Serial Bus connection between said memory card and a peripheral device.

4. A memory card interface apparatus as in 1, further comprising a mass storage to parallel interface coupled to said internal bus and to one of said plurality of external connectors, thereby supporting communication through a mass storage to parallel connection between said memory card and a mass storage device.

5. A memory card interface apparatus as in 4, wherein said mass storage to parallel interface includes an ATAPI interface.

6. A memory card interface apparatus as in 4, wherein said mass storage to parallel interface includes a SCSI interface.

7. A memory card interface apparatus as in 1, further comprising a television signal converter coupled to said internal bus and to one of said plurality of external connectors, thereby supporting communication through a parallel port connection between said memory card and a television.

8. A memory card interface apparatus as in 1, further comprising a sound signal converter coupled to said internal bus and to one of said plurality of external connectors, thereby supporting communication through a parallel port connection between said memory card and an audio device.

9. A memory card interface apparatus as in 1, further comprising a memory to ATAPI converter coupled to said internal bus, thereby supporting communication between said memory card and said interface controller through a ATAPI interface.

10. A memory card interface apparatus as in 1, wherein said device coupled to one of said plurality of external connectors includes a host computer, and said one of said plurality of external connectors includes a parallel interface.
