Cross point array with fast access time. A cross point array is driven by
drivers on a semiconductor substrate. The drivers for either a
single-layer cross point array or for the bottom layer of a stacked cross
point array can be positioned to improve access time. Specifically, if
the x-direction drivers are positioned in the middle of the x-direction
conductive array lines and the y-direction drivers are positioned in the
middle of the y-direction conductive array lines, the access time will be
improved.
