    Abstract: A display driver circuit may include a revision controller for controlling a nonvolatile memory having instructions by which control data for controlling devices controlled by the display driver circuit are changed, and a drive controller for controlling the devices based on the instructions. The revision controller determines whether to perform a read operation to the instructions based on electrical power being applied to the display driver circuit, and transfers instruction signals, which are generated based on the determination to perform the read operation, to the driving controller.

    Abstract: A memory device includes a memory cell array, a sense amplifier, a voltage generation circuit and a control circuit. The memory cell array includes a plurality of bit lines to which a plurality of memory cells are connected, and a shielding bit line arranged between the plurality of bit lines and on lower portions of the plurality of bit lines. The sense amplifier is configured to sense and amplify data stored in a memory cell selected from among the plurality of memory cells. The voltage generation circuit is configured to generate a bit line precharge voltage and an internal power voltage based on a power voltage of the memory device. The control circuit is configured to selectively provide the shielding bit line with the bit line precharge voltage or the internal power voltage.
