CIRCUIT AND METHOD FOR DETECTING TAMPERING OR PREVENTING FORGERY OF SEMICONDUCTOR CHIP |
| 摘要 |
A circuit for preventing forgery of semiconductor chip includes a driving signal protection unit and a control unit. The driving signal protection unit configured to include at least one protection wire protecting a driving wire having driving signals flow therethrough. The control unit configured to generate a first security code and a second security code. The control unit is further configured to compare the first security code that passes through the driving signal protection unit and the second security code that bypasses the driving signal protection unit to detect tampering at the at least one protection wire, and to control operation of the semiconductor chip. |
