SEMICONDUCTOR DEVICE AND INFORMATION PROCESSING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor circuit device and an information processing apparatus that ensure a stable operation.

SOLUTION: The semiconductor device comprises: a delay section for delaying an input signal; a phase detection section for detecting a phase of an output signal output from the delay section; a setting section for setting a stable operation range of the phase of the output signal according to phase information output from the phase detection section; a counter for counting the number of times when the detected output signal has a phase deviating from the stable operation range; a discount control section for generating a discount signal indicating a discount number for the count number of the counter in accordance with an operation condition of the delay section or an external factor; and an error determination section for determining whether or not the phase of the output signal is an error according to the count number of the counter and the discount number indicated by the discount signal.
