Methods, apparatuses, and systems related to calibrating memory circuitry according to externally provided reference voltage are described. A memory device may include a calibration control logic that at least isolates an internal reference voltage from an internal buffer. The internal buffer may receive and process the externally provided reference voltage instead of command-address signals for calibration purposes.

Methods, systems, and devices for memory device random option inversion are described. A memory device may use a second set of fuses to selectively invert options associated with a first set of fuses (e.g., blown fuses). The first set of fuses may output a first set of logic states. Option inversion logic circuitry may perform decoding based on a second set of logic states output by the second set of fuses to identify logic states of the second set of logic states that match the first set of logic states. Based on identifying the logic states, the option inversion logic circuitry may select either a logic state of the first set of logic states or an inverted logic state corresponding to the logic state, and store the selected logic state in a latch of the memory device.

Apparatuses and methods for capturing data in a memory are disclosed herein. An apparatus may include a command path and a data capture logic. The command path may be configured to receive a command signal and to delay the command signal with a delay based, at least in part, on a plurality of propagation delays. The data capture logic may be coupled to the command path and configured to receive the delayed command signal and a data strobe signal. The data capture logic may further be configured to capture data according to the data strobe signal responsive, at least in part, to receipt of the delayed command signal.
