Driver unit including common level shifter circuit for display panel and nonvolatile memory

摘要

In a driver unit for driving a display panel and a nonvolatile memory, a level shifter circuit receives a driver control signal to generate a level-shifted driver control signal. A display panel driver circuit drives the display panel in accordance with the level-shifted driver control signal. A nonvolatile memory driver circuit drives the nonvolatile memory in accordance with the level-shifted driver control circuit. A selection circuit selects one of the display panel driver circuit and the nonvolatile memory driver circuit.
