Abstract
The invention provides SRAMs that can reduce memory cells in size and correct light proximity effect. Gate electrode layers in a first layer, drain-drain connection layers in a second layer, and drain-gate connection layers in a third layer define conduction layers of a flip-flop. A source contact layer of load transistors are located adjacent end sections of the gate electrode layers, and both of the end sections bend outwardly to avoid contact with the source contact layer.
