A semiconductor storage device has a sense amplifier. The direction and the speed of the rotation for the pin tool may be selected independently from the speed and direction of rotation of the shoulder tool enabling optimization of the friction stir welding process. The connection arrangement is comprised by a pin with a head or head arrangement, engaging positions, and a retaining element. A method of driving a multi-channel semiconductor memory device including a plurality of memories, using a shared bus, is also provided. This table is updated with information relating to the IP address when, for example, the network access identifier changes, when a point-to-point protocol timer expires, when an IP registration expires a location of the terminal changes.
