Data input buffer in semiconductor device

[0023] In accordance with the present invention, current driving capability of a data input buffer is adjusted by using sensing result that is obtained with a temperature sensor and / or process characteristic sensor. For this purpose, the present invention applies an element for adjusting current amount flowing through a data input part and a reference voltage input part step by step, and an element for making a current control signal from the sensing result. With the present invention, even under worst-case process characteristic or high temperature condition, operation speed deterioration of the data input buffer can be avoided.

[0024] Hereinafter, a data input buffer in a semiconductor device in accordance with the present invention will be described in detail referring to the accompanying drawings.

[0025]FIG. 2 provides a circuit diagram of a data input buffer in accordance with one embodiment of the present invention.
