Apparatuses and methods for adjusting delay of command signal path

Abstract:

Apparatuses and methods related to adjusting a delay of a command signal path are disclosed. An example apparatus includes: a timing circuit that includes a divider circuit that receives a first clock signal having a first frequency and provides a complementary pair of second and third clock signals having a second frequency that is half the first frequency; a first delay circuit that receives the second clock signal and provides a delayed second clock signal responsive to the second clock signal; and a second delay circuit that receives the third clock signal and provides a delayed third clock signal responsive to the third clock signal. The timing circuit receives a first signal, latches the first signal responsive to the delayed second clock signal to provide a second signal and latches the second signal responsive to either the second clock signal or the third clock signal responsive to latency information.
