Abstract: Apparatuses and methods for wide clock frequency range command paths are disclosed. An example apparatus includes a command decoder and a command timing circuit. The command decoder is configured to receive a command and is further configured to decode the command to provide a decoded command. The command timing circuit is configured to receive the decoded command responsive to a clock and is further configured to provide a delayed internal command having a delay relative to receiving the decoded command based on clock frequency information indicative of a clock frequency of the clock. The command timing circuit includes a plurality of command timing paths. Each of the plurality of command timing paths is configured to provide a respective delay to the decoded command for a respective range of clock frequencies.
