ABSTRACT:
An embodiment of the invention is a method for measuring access time where the frequency of a ring oscillator is measured with and without a device under test1in the ring. Those two frequencies are compared to calculate the access time of the device under test1. Another embodiment of the invention is circuitry25that measures the frequency of a ring oscillator with and without a device under test1. Again the two frequencies are compared to calculate the access time of the device under test1.
