In embodiments, a system and method for providing a lifecycle for information in virtual content repository are provided. Also provided are optoelectronic modules and methods of forming optoelectronic components. The control circuit is operable to compare each of the data bits provided for storage in a corresponding one of the memory cells having a stuck-at fault to a value of the stuck-at fault, and to invert each of the data bits having a different value than the value of the stuck-at fault of the corresponding one of the memory cells to generate encoded data bits. The power source lines of the reference potential connected to the repeater regions 10 are laid out at equally spaced intervals throughout the core power source regions 2 to 8, which enables the repeater regions 10 to be flexibly laid out. The apparatus is also suitable for maintaining the relative phase of two beams of radiation, during translation of an optical subsystem.
