Abstract
In some examples, a first delay path and a second delay path may each be configured to receive a signal as an input signal at the same time, propagate the input a plurality of MRAM cells, and output the propagated input signal for an arbiter. The arbiter may be configured to output a response value based at least in part on a relative order of arrival of the propagated input signals from the first and second delay paths.
