An array of non-volatiel memory cells arranged in logical columns and logical rows, and associated circuitry to enable reading or writing one or more memory cells on a row in parallel. The present invention is also directed to a 360 degree ventilation system with a single mixing chamber extending at least substantially entirely around the perimeter of the blow ventilation system. In another aspect, a storage router is communicatively connectable to a plurality of target storage devices. The deflector assembly comprises a first and second deflector that lie one behind the other in the course of the thread, one of Which transmits the stress from the thread tension and the other the stress from the pathhalt conditions to a respective transducer device.
