Abstract
In a semiconductor memory device, a reference delay section has a first delay value and delays a first signal by a reference delay value obtained from the first delay value and an adjustment value while changing the adjustment value, and fixes the adjustment value when the first signal and the delayed first signal meet a predetermined condition. A delay section has a second delay value and generates an output signal based on a summation of the fixed adjustment value and the second delay value, and a set multiplication value in response to a trigger signal such that the output signal in an active state for a period corresponding to the set multiplication value.
Claims8
A semiconductor device comprises:
- a reference delay section having a first delay value and configured to delay a first signal by a reference delay value obtained from said first delay value and an adjustment value while changing said adjustment value, and to fix said adjustment value when said first signal and the delayed first signal meet a predetermined condition;
- and
- a delay section having a second delay value, and configured to generate an output signal based on a summation of the fixed adjustment value and said second delay value, and a set multiplication value in response to a trigger signal such that said output signal in an active state for a period corresponding to said set multiplication value.
