A semiconductor package is disclosed including test pads formed of solder bumps affixed to the semiconductor package during fabrication. The reset state of a bit line is canceled when selected and connected to a read circuit for read, and information stored in a selected memory cell is read via the selected bit line. One cable is attached to the body and another is attached to the turret, so they are also relatively rotatable. The earphone may include a fastener that removably mounts the nozzle to the housing so that the nozzle may be readily removed and cleaned or replaced. The method for high speed rerouting in a multi protocol label switching network, the method comprising the steps of controlling a traffic stream to flow in a reverse direction in a point where a node or link failure occurs by using a backup Label Switched Path comprising an Explicitly Routed LSP having a reverse tree of a protected multi point to point LSP and an ingress LSR through an egress LSR.
