1. A data serializer, comprising:
at least one data buffer, at least receiving an inputting data and a controlling signal, wherein an outputting signal and a complementary outputting signal, which is complementary to the outputting signal, are formed when the controlling signal is at a predetermined level; and
a de-skew buffer, receiving the complementary outputting signal to accelerate or slow down forming the outputting signal,
wherein the de-skew buffer includes a PMOS transistor connected to the data buffer, rising of the outputting signal is slower than falling of the outputting signal, and the PMOS transistor of the de-skew buffer is turned on to pull the outputting signal high.
