A memory device such as a 6F2 memory device includes isolation trenches that are formed generally parallel to and along associated strips of active area. The circuit uses few components, each of which is independent of parameters such as switching frequency, duty-cycle, and filament resistance, and is therefore compact, cost-effective, and efficient. The pressure switch 8 can be subjected to a measured pressure via a pneumatic measurement line 7, which is separate from the supply line, and this measured pressure characterizes a state of the operating pressure of the consumer. When a ball is thrown by a pitcher and it strikes the target arm, the target section will partially rotate around the anchor support post. The at least one locking pin locks the assembly by rotation of the fastening hinge post body within the channel in the bushing body. The trench depth corresponds to the maxima peak separation.
