Abstract
Systems and apparatuses are provided for an arbiter circuit for timing based ZQ calibration. An example system includes a resistor and a plurality of chips. Each of the plurality of chips further includes a terminal coupled to the resistor, a register storing timing information, and an arbiter circuit configured to determine whether the resistor is available based, at least in part, on the timing information stored in the register. The timing information stored in the register of each respective chip of the plurality of chips is unique to the respective chip among the plurality of chips.
