Abstract
Methods and systems for determining a memory access time are provided. A first phase skew is measured between a first clock signal used by a memory and a second clock signal used as a reference clock signal. Then, a second phase skew is measured between a delayed version of the first clock signal output by the memory when the memory completes a given read operation and the second clock signal. The memory access time is determined based on the first and second phase skews.
