A roof and rack assembly for an automotive vehicle includes a roof panel received from polymeric organic material that has a top surface and edges, extending between a first or front and a second or rear ends of the roof panel. Logic for identifying conflicting messages is provided at the data management system by comparing key information in data fields. The on-die distributed programmable passive variable resistance memory array is used as either non-volatile prepackage configuration information store, or a non-volatile post-package configuration information store that may allow dynamic changing of hardware configuration of the functional blocks both during normal operation and prior to die packaging.
