Systems and methods for advertising routing updates are disclosed. Because a resistor formed by such a process can include an aligned body and contact, it often occupies a smaller area than prior integrated resistors having a similar resistance value. The first mirror surface is adapted to reflect and collimate light emission from the optical emitter. The selection circuitry includes line drivers that select a storage component of a memory tile based on a corresponding digit line conductor and a corresponding access line conductor to the storage component.
