Semiconductor IC device with word lines shielded from voltage changes in adjacent lines

摘要

A semiconductor IC device has word lines which are sequentially arranged and each connected to the gate of a MOS transistor such that its drain and source are individually connected to the adjacent word lines. Either of these adjacent word lines is connected to a fixed potential source such that potential changes in selected one of these word lines are electrically shielded and do not affect the non-selected other word lines in the device.
