Abstract: Apparatus, methods, and systems are disclosed, such as those involving a multi-die device having a common bus to indicate a state of each of a die of a multi-die device and that provides the state of all of the dice at a common output. Such a multi-die device can comprise two or more dice in a multi-die package, wherein each of said dice has a first drive parameter when indicating a first state and a second drive parameter when indicating a second state. When the first drive parameter of the two or more dice is at a value such that when one or more of said two or more dice is in the first state, said common output can indicate that all of the dice in the multi-die device are in the first state.
