A semiconductor memory with multiple timing loops for optimizing memory access operations. The invention creates and presents advertising content founded on individual user profiles integrated with the physical geographic location of a consumer. A process of making irradiated crosslinked polyethylene composition having reduced free radical content, preferably containing substantially no residual free radicals, by mechanically deforming the polyethylene at a temperature that is below the melting point of the polyethylene, optionally in a sensitizing environment, is also disclosed herein.
