Abstract

A cross-point switching array in which each cross-point of the array is controlled by the output of a first memory. Each first memory is associated with a second memory. The second memories can be sequentially set by a single controller while the cross-point connections are maintained according to the first memories. The contents of all second memories are concurrently loaded into the associated first memories to simultaneously reconfigure the cross-point array.
