Abstract: Some embodiments include apparatus and methods using a first ring oscillator, a second ring oscillator, and circuit coupled to the first and second ring oscillators. The first ring oscillator includes a first memory cell and a first plurality of stages coupled to the first memory cell. The second ring oscillator includes a second memory cell and a second plurality of stages coupled to the second memory cell. The circuit includes a first input node coupled to an output node of the first ring oscillator and a second input node coupled to an output node of the second ring oscillator. In one of such embodiments, the circuit can operate to generate identification information to authenticate the apparatus.

Abstract: Embodiments include apparatuses, methods, and systems for voltage level shifting a data signal between a low voltage domain and a high voltage domain. In embodiments, a voltage level shifter circuit may include adaptive keeper circuitry, enhanced interruptible supply circuitry, and/or capacitive boosting circuitry to reduce a minimum voltage of the low voltage domain that is supported by the voltage level shifter circuit. Other embodiments may be described and claimed.
