The subject invention pertains to novel materials and methods for use in treating patients afflicted with oncological disorders, such as tumors. The data-lines are arranged in a region between the first and second nonvolatile memory banks, and selectively connected to the bit-lines of the first and second nonvolatile memory banks. The first component is an inner lens, while the second component may be a reflector or a second lens. The layers are enclosed in a flexible pouch, and the first and second conductive tabs are extended through seals in the pouch to provide terminals for the battery cell.
