Data transmission circuit, data transmission method and storage device

A storage device, comprising:

• a storage cell array, configured to store array area data;
• a mode register, configured to store a setting parameter;
• and
• a data transmission circuit, wherein the data transmission circuit comprises:
• a controllable delay module, configured to generate a delayed read command in response to a mode register read command;
• and
• a mode register data processing unit, connected to the controllable delay module, and configured to read a setting parameter from the mode register in response to the mode register read command, and to output the setting parameter in response to the delayed read command;
• wherein a time difference between a start moment of outputting of the setting parameters and a moment when the controllable delay module receives the mode register read command is a first preset threshold.

A data transmission method, comprising:

• controlling a controllable delay module to generate a delayed read command in response to a mode register read command;
• reading a setting parameter from a mode register based on a mode register data processing unit in response to the mode register read command;
• and
• outputting the setting parameter based on the mode register data processing unit in response to the delayed read command, wherein a time difference between a start moment of outputting of the setting parameters and a moment when the controllable delay module receives the mode register read command is a first preset threshold.
