Abstract:
Methods and apparatuses are provided for dynamic step size for impedance calibration of a semiconductor device. An example apparatus includes a resistance calibration circuit configured to provide an impedance code to set impedance of a driver circuit. The resistance calibration circuit includes an adder/subtractor circuit configured to change the impedance code by a first step size responsive to the impedance code being less than a value to adjust the impedance of the driver circuit and further configured to change the impedance code by a second step size responsive to the impedance code greater or equal than the value to adjust the impedance of the driver circuit. The second step size is different from the first step size.

Claim (Index 3):
The apparatus of  claim 1  wherein the address/subtractor circuit comprises:\n a plurality of full adder circuits; \n a plurality of XOR gates, each configured to provide an output to a respective one of the full adder circuits; \n a NAND gate configured to provide an output based on a logical operation of a portion of bits of the impedance code; \n a first multiplexer configured to provide the output to a first one of the plurality of XOR gates, the output selected from the output of the NAND gate or a bit value of the portion of bits of the impedance code based on the output of the NAND gate; and \n a second multiplexer configured to receive outputs from the plurality of full adder circuits and to receive a maximum impedance code, the second multiplexer further configured to provide as the impedance code the outputs from the plurality of full adder circuits or the maximum impedance code based on a carry out bit from a last one of the plurality of full adder circuits.
