    摘要: Disclosed is a source driver integrated circuit with an improved slew rate by disposing a switching unit, which operates as a resistance component during display driving, before the feedback line of an output buffer. According to the source driver integrated circuit with an improved slew rate, a switching unit, which operates as a resistance component when a signal is transferred, is disposed in the feedback loop of an output buffer, so that the resistance component is not shown to a panel load, thereby improving the slew rate of an output signal. In addition, the improved slew rate makes it possible to easily implement an image through a display.

    摘要: A semiconductor memory device according to the present invention includes a write pulse width timing compensating part that controls a write pulse width timing. The semiconductor memory controls the point of disabling a write control drive signal by directly producing a write enable signal or delaying the write enable signal based on a level of a power supply voltage to compensate the write pulse width timing. The write pulse width timing compensating part receives the poser supply level and the write enable signal and outputs a compensated write control drive signal. A generating part receives the write control drive signal from the write pulse width timing compensating part, a selection signal, and a decoder signal and generates a control signal. A data input part writes input data to a selected cell upon application of data and the control signal from the generating part.
