Variable delay circuit, memory control circuit, delay amount setting apparatus, delay amount setting method and computer-readable recording medium in which delay amount setting program is recorded
A variable delay circuit being able to change a delay amount from when a signal is inputted to when the signal is outputted has a first delay section delaying the signal by a first delay amount, a second delay section delaying the signal by a second delay amount greater than the first delay amount, and a delay amount selector selecting a signal route where the delay amount is a sum of the first delay amount and the second delay amount when the delay amount exceeds a maximum delay amount delayable by the first delay amount section. The delay amount from when a signal is inputted to when the signal is outputted can be set in a wide range, while suppressing the circuit scale.
