METHOD AND APPARATUS FOR SCRAMBLING CELL CONTENT IN AN INTEGRATED CIRCUIT

摘要

The invention provides a system for scrambling data in a sequential cell. The sequential cell is configured to receive the data from a data bus. A scrambling unit is coupled to the sequential cell and the data bus. The scrambling unit is configured to receive a scrambling unit input from the data bus and produce a scrambling unit output that differs from the scrambling unit input. The scrambling unit output is transmitted to the sequential cell. A descrambling unit is coupled to the sequential cell and is configured to receive a descrambling unit input from the sequential cell and produce a descrambling unit output that differs from the descrambling unit input. The descrambling unit output is equal to the scrambling unit input.
