Abstract
A semiconductor chip comprises at least one data bus to transmit data processed by the semiconductor chip, an electric potential generator block packaged together with the at least one data bus to be blocked from external light by a package, the electric potential generator block to detect an event in which the package is unable to block the external light, and a switch configured to block a transmission of at least some data in the at least one data bus if the event is detected. A semiconductor chip comprises an energy harvesting element inside a package. The energy harvesting element may comprise an on-chip photodiode. A depackaging attack causes the generation of a voltage of a photodiode, and thus a change in physical state of the packaging can be detected.
