Binary Encoding Logic Circuits    

Increase in disk drive density without an increase in cost or power consumption.

Overview

20% increase in density without an increase in cost or power consumption. This circuitry was proven in silicon at Rohm in Japan. Lastly, this IP can also be used by vendors developing solid-state memory replacements for hard disk drives. Why? Because the same density advantage will be realized ... so a 10GB memory stick will become 12GB with this IP. Its a direct relationship between density and the use of their patents.

Patent Summary

U.S. Patent Classes & Classifications Covered in this listing:

Class 703: Data Processing:Structural Design, Modeling, Simulation, And Emulation

This class provides for electrical data processing apparatus and corresponding methods for the following processes or apparatus: 1. for sketching or outlining of layout of a physical object or part. 2. for representing a physical process or system by mathematical expression. 3. for modeling a physical system which includes devices for performing arithmetic and some limited logic operation upon an electrical signal, such as current or voltage, which is a continuously varying representation of physical quantity. 4. for modeling to reproduce a nonelectrical device or system to predict its performance or to obtain a desired performance. 5. for modeling and reproducing an electronic device or electrical system to predict its performance or to obtain a desired performance. 6. that allows the data processing system to interpret and execute programs written for another kind of data processing system.

Subclass 2: MODELING BY MATHEMATICAL EXPRESSION

Class 375: Pulse Or Digital Communications

This is the generic class for pulse or digital communication systems using electrical or electromagnetic signals. Such communication includes transmitting an intelligence bearing signal from one point to another in the form of discrete variations in some parameter of the electrical or electromagnetic signal.
