A memory device may include sideband circuitry to provide additional functionality without interfering with normal operations of the memory device. The memory device may also include sideband pins to provide sideband information to an external device. The sideband information may include various digital or analog signals. In some cases, a sideband circuit of the memory device may use a data protocol for communicating the sideband information with the external device. Furthermore, systems and methods for receiving sideband information from multiple memory devices of a memory system are described to reduce latency and increase functionality of a memory system including such memory devices.
