Abstract: Apparatuses and methods for temperature independent oscillator circuits are disclosed herein. An example apparatus may include a pulse generator circuit configured to provide a periodic pulse based on the charging and discharging of a capacitor and further based on a reference voltage. The pulse generator circuit may include a capacitor coupled between a first reference voltage and a first node, wherein the capacitor is configured to be charged and discharged through the node in response to the periodic pulse, a resistor and a diode coupled in series between a second node and a second reference voltage, and a comparator coupled to the first and second nodes and configured to provide the periodic pulse based on voltages on the first and second nodes, wherein a period of the periodic pulse is based at least on the resistor and the a current.

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.
