Abstract
An integrated circuit (IC) device can include at least one phase or delay lock loop (P/DLL) circuit comprising a plurality of circuit sections, at least one of the circuit sections responsive to digital calibration values to alter at least one periodic output signal; a nonvolatile memory (NVM) circuit formed in the same IC package as the at least one P/DLL circuit and configured to store the calibration values; and a processing circuit formed in the same IC package as the at least one P/DLL circuit and the NVM circuit, the processing circuit configured to generate the calibration values in response to target values and output values from the at least one P/DLL circuit, and to store the calibration values in the NVM circuit.
