DESCRIPTION:     The architecture of a multiplexed charge-locking device [
 1] could enable the control of a large number of gates with reduced number
  of electrical contacts\, representing itself as a useful tool for up-scal
 ing of a quantum dot system. Nevertheless\, two problems were found from p
 revious operation experience of such devices\, which hinder their further 
 applications in forming larger arrays of quantum dots. The first problem i
 s a drift in voltage from a floating (charged) gate\, which has been discu
 ssed in the above reference. The second problem is the leakage of charge (
 from the first addressed gate) when\, for example\, two next to nearest ga
 tes are addressed successively\, partly due to the nature of the multiplex
 er.\n     In this presentation\, I will show various operations of the mul
 tiplexed charge-locking device towards resolving the above two problems.\n
