Abstract
An open loop type delay locked loop includes a delay amount pulse generation unit configured to generate a delay amount pulse having a pulse width corresponding to a delay amount for delay locking a clock signal, a delay amount coding unit configured to output a code value by coding the delay amount in response to the delay amount pulse, a clock control unit configured to adjust a toggling period of the clock signal in response to a control signal, and a delay line configured to delay an adjusted clock signal outputted from the clock control unit in response to the code value.
