In a semiconductor memory device with a plurality of banks having a plurality of memory sub array, according to a mode setting signal, data access control is made depending on whether access is made on a memory sub array basis or a bank basis. The lens is traced utilizing the specifically designed invention pen, and scanned into a software system which retrieves the traced image and plots a lens shape based upon a calculated distance between first color template axis indicators and a second color pen tracing. The lower frame is adapted to move in a substantially vertical direction and movement in a substantially vertical direction of the lower frame results in corresponding substantially vertical movement of the screed extension. A soft magnetic composite core for the smart sections is disclosed. When a backup or restore is performed, the system checks the media label to ensure that the correct media is being used.
