    摘要: A system that selectively couples one or more IC chips to card slots. The system contains a Z-bar switch which includes: a select input; a first IC port coupled to a first IC pin; a second IC port coupled to a second IC pin; a first card slot port coupled to a first card slot pin; and a second card slot port coupled to a second card slot pin. If the select input receives a first control pattern, the Z-bar switch is configured to: couple the first IC port to the first card slot port; and to couple the second IC port to the second card slot port. If the select input receives a second control pattern, the Z-bar switch is configured to: couple the first IC port to the second card slot port; leave the second IC port floating; and to leave the first card slot port floating.
