In some examples, command decoders may have multiple command paths. In some examples, command signals from one command path may be provided to another command path from a node located between two latches of the command decoder, such as two latches of a flip-flop. In some examples, the command decoder may include separate flip-flops for different command modes. In some examples, the separate flip-flops may be tristate flip-flops. In some examples, the command decoder may include alternate logic circuits rather than a multiplexer.

Apparatuses and methods for command decoding

Apparatuses and methods for command decoding with series connected latches

Apparatuses, systems, and methods for bias temperature instability (BTI) mitigation. A BTI oscillator provides a periodic BTI signal. A BTI logic circuit generates a BTI pulse signal based on the periodic BTI signal and synchronized to a clock signal. A clock gating circuit passes the clock signal to a clock path when the periodic BTI signal is active. When the memory is in an unclocked mode, where an external clock is not received, the periodic BTI signal is provided to a clock input buffer and passed as the clock signal.

Apparatuses and methods for bias temperature instability mitigation

An apparatus, such as a memory device, that includes circuits and techniques to synchronize various internal signals with an internal clock signal to ensure proper functionality of the memory device through various modes of operation. A clock enable control circuit is provided to control the input of a delay locked loop circuit to provide a locked condition based on a particular type of command input and the state of various control signals to allow for multiple locking conditions and adjustments based on a length of a clock cycle of the internal clock signal.
