A memory module is described having a memory array storing data, an ID information output circuit for outputting ID information for identifying memory modules, and output switching means for selectively switching between output from the memory array and output from the ID information output circuit, and output from the ID information output circuit will be selected instead of output from the memory array until the memory module is initially written after the power supply to the memory module has been started. This enables a memory module to be identified without having to add parts to a computer system unit or providing a ROM storing a specification or the like to the memory module.

A liquid crystal display comprises an input for inputting a video signal from a host and a storage medium for storing the previous brightness level of the video signal input through the input. A determinator is provided for determining an output brightness level based on the previous brightness level stored in the storage medium and the next brightness level of the next video signal input to the input, so as to make the time integration quantity of a brightness change substantially equal to an ideal quantity of light in a stationary state with respect to the next brightness level. Further included are drivers for driving an image displaying liquid crystal cell based on the output brightness level determined by the determinator.
