Integrated digital circuit has unit for checking signal in circuit for error during normal mode, changing to special mode with lower operating frequency and failure probability if error detected

摘要

The integrated digital circuit has a unit for checking a signal in the digital circuit for an error during a normal operating mode of the circuit and for changing over to a special mode with a lower than normal operating frequency if an error is detected. The special operating mode has a lower failure probability than the normal operating mode. AN Independent claim is also included for the following: a method of operating an inventive device.
