Abstract: A new architecture for use with computer memory storage devices is disclosed that provides means by which a memory storage device may be accessed both as standard archive file device as well as in any unique physical and native command set modes supported by the device. A system architecture for accessing a memory storage device that provides access to the storage device via a standard memory storage method while alternatively providing direct access to the full physical and functional capabilities of the storage device. The system architecture has four main elements. Firstly, a central processing system which acts as the user interface and controls access to all attached peripheral functions. Secondly, an electronic bridge connected on one side to the central processing system via a standard I/O channel and on the other side to the memory device through a memory bridge presenting the memory device to the central processing system as a standard memory peripheral.

Abstract: In order to greatly simplify the electronics of devices utilizing memory cards, a new type of interface specification is presented which is called DPXD for a “Dual Ported eXtended Digital” memory card. The DPXD interface specification comprises an electrical 5 signal set definition based upon a new dual USB concept call Dual Ported USB or DPUSB, a mechanical and electrical definition for a memory card socket, an associated memory card signal and mechanical specification for a memory card, and a mechanical definition for cables compatible with the DPXD socket.

Abstract: A dual port interface is disclosed comprising a host port and a peripheral port. The host port and the peripheral port are defined using predetermined signals. In a preferred embodiment the dual port interface is used in a network comprising one or more a dual port USB (DPUSB) connectors. By use of the DPUSB interface, both one-to-one and one-to-many network topologies can be created. Use of the DPUSB interface also provides the opportunity of new types of devices such as memory cards and cables that will greatly increase the ease of use of many intelligent electronic devices such as cameras and PDAs.

Abstract: A universal memory bus coupled between a system's CPU and the system memory is composed of four channels; a primary channel, an identification channel, a programming channel and an expansion channel. The primary channel communicates operating system data necessary to boot the system. The identification channel communicates signals describing the device composition of the system memory. The programming channel communicates programming signals to all of the programmable memory devices within the system memory and thus allows complete programmability of those devices. The expansion channel provides data and programming access to a memory device subsequently added to the system memory.
