Information retrieval device for displaying and directly refreshing the display of a document

An information retrieval device for displaying a document, comprising:

• non-volatile memory for storing said document;
• a plurality of input selector switches:
• a display screen;
• controller circuitry connected to said non-volatile memory, said input selector switches, and said display screen, said controller circuitry determining which portion of said document to display on said display screen, responsive to said plurality of input selector switches;
• said controller circuitry refreshing said display screen directly from said non-volatile memory, said controller circuitry further comprising;
• a microcontroller cell;
• an object register for storing a plurality of hypertext object states;
• and
• a switch selection register for storing a current switch status.

An information retrieval device for displaying a document, comprising:

• non-volatile memory for storing said document;
• a display for displaying said document;
• and
• means for refreshing said display directly from said non-volatile memory.

A method for generating and displaying a document on a display screen, comprising the steps of:

• reading initial state data from non-volatile memory;
• determining a first display state from said initial state data;
• displaying on said display screen a first portion of said document from a first document portion of said non-volatile memory corresponding to said first display state;
• and
• refreshing said display screen directly from said non-volatile memory.

A non-volatile memory for storing a document used by an information retrieval device, said non-volatile memory pluggable into said information retrieval device, said memory comprising:

• a first section addressable by said information retrieval device, said first section comprising initial state data;
• a second section addressable by said information retrieval device, said second section comprising said state machine;
• a third section addressable by said information retrieval device, said third section comprising a first portion of said document;
• a fourth section addressable by said information retrieval device, said fourth section comprising a second portion of said document;
• said first section also comprising a pointer to said state machine;
• said first section also comprising a pointer to said first portion of said document;
• said state machine comprising a pointer to said first portion of said document for display by said information retrieval device when in a first display state;
• and
• said state machine also comprising a pointer to said second portion of said document for display by said information retrieval device when in a second display state.

A method of storing a document on a non-volatile memory used by an information retrieval device, said non-volatile memory pluggable into said information retrieval device, said method comprising:

• generating and storing a first section addressable by said information retrieval device, said first section comprising initial state data;
• generating and storing a second section addressable by said information retrieval device, said second section comprising said state machine;
• generating and storing a third section addressable by said information retrieval device, said third section comprising a first portion of said document;
• generating and storing a fourth section addressable by said information retrieval device, said fourth section comprising a second portion of said document;
• generating and storing in said first section a pointer to said state machine;
• generating and storing in said first section a pointer to said first portion of said document;
• generating and storing in said state machine a pointer to said first portion of said document for display by said information retrieval device when in a first display state;
• and
• generating and storing in said state machine a pointer to said second portion of said document for display by said information retrieval device when in a second display state.
