A computer implemented method handles service requests for HTTP-based services via IP ports that are located on HTTP servers. More specifically, embodiments of the present invention include processor-based systems with volatile-memory having memory devices that include a die having a circuit configured for enablement by a particular signal, an input pin configured to receive the particular signal, and a path selector configured to selectively designate a signal path to the circuit from the input pin. The marked segments are created by the application of assorted quanta of radiant energy from the laser.
