Command processing circuit and data processing circuit

A command processing circuit, comprising a plurality of flip-flops arranged in sequence, an output terminal of a former one of the plurality of flip-flops being connected to an input terminal of a latter one of the plurality of flip-flops, the plurality of flip-flops being configured to sample, according to switching of a data strobe signal, an internal write command inputted into the command processing circuit to obtain a sampling command, the sampling command being configured for sampling data;

• wherein an output terminal of a target flip-flop in the plurality of flip-flops is connected to a target terminal of a first one of the plurality of flip-flops, the target flip-flop being a flip-flop whose time of outputting an active level overlaps target time, the target time being start time and/or end time of a pulse in the internal write command;
• and
• wherein the target flip-flop is configured to reset the internal write command in the first flip-flop by outputting the active level.
