ABSTRACT:
An integrated circuit bit line driver system includes a plurality of bit line drivers coupled to respective bit lines of an array of non-volatile memory cells. Each of the bit line drivers includes a bias transistor through which an input signal is coupled to the respective bit line. The bit line driver system includes a bias voltage circuit that generates a bias voltage that is coupled to the respective gates of the bias transistors. The bias voltage circuit initially accelerates the charging of the transistor gates, and subsequently completes charging the gates at a slower rate. The bias voltage is generated using a diode-coupled transistor having electrical characteristics the match those of the bias transistors so that the bias voltage varies with process or temperature variations of the integrated circuit in the same manner as the threshold voltage of the bias transistors vary with process or temperature variations.
