An electroluminescence device includes a tubular first electrode, an electroluminescence layer formed on an inner surface of the first electrode, and a second electrode formed on an inner surface of the electroluminescence layer. Visual mapping software on a computer provides a visual mapping interface in which a user can create, edit, andor view a visual map. The alkali metal ions contained by the edge seal may be Li+, Na+, K+, Rb+, andor Cs+, and may be included as a dopant with the material of the edge seal during its formation, or may be included as a discrete component of the edge seal, as by an ion-doped strip of membrane material contained by the edge seal. The multi-bit output increments by a predetermined amount in response to each reference clock period. To facilitate execute-in-place functionality across the multiple XIP regions, a virtual address table is generated to store pointers to the objects stored in the non-volatile memory hosting the multiple XIP regions.
