Claim 0:
1. A data transmission method, comprising:
generating a delayed read command based on a delay module responding to a mode register read command, wherein an operation delay of the delay module is the first preset time, wherein the delay module comprise a first delay unit, a second delay unit, and a third delay unit;
responding to the mode register read command, and reading setting parameters from the mode register based on a mode register data processing unit;
wherein the mode register data processing unit outputs the setting parameters, in response to the delayed read command;
generating, by the first delay unit of the delay module, a first delayed read command after a second preset time delay, when the mode register read command is received;
generating, by the second delay unit of the delay module, a second delayed read command after a third preset time delay when the first delayed read command is received, and wherein the third preset time equals to an operation delay of a column selection control module; and
generating, by the third delay unit of the delay module, a third delayed read command after a fourth preset time delay, when the second delayed read command is received;
wherein generating by the third delay unit of the delay module further comprises:
generating, by a first sub-delay unit of the third delay unit of the delay module, a third delayed read command after a fifth preset time delay, when the second delayed read command is received, wherein the fifth preset time is equal to an operation delay of a read-write amplifier; and
generating, by a second sub-delay unit of the third delay unit of the delay module, a first delayed read command after a sixth preset time, when the third delayed read command is received, wherein, a sum of the fifth preset time and the sixth preset time is equal to the fourth preset time;
wherein, a sum of the second preset time, the third preset time, and the fourth preset time is equal to the first preset time.
