A method and system are provided for controlling clock operation in a memory that applies a test mode to test functionality of the memory which controls timing in a self-time loop using an external clock that on a rising edge triggers a main clock and on a falling edge provides a reset timer return path to reset the main clock signal. In the reset timer return path, a rising edge of the external clock triggers start of a self-time loop, and the rising edge of the external clock also controls the reset timer return path to block generation of a reference bit line (RBL) signal. In the reset timer return path, a falling edge of the external clock generates the RBL signal to provide an external clock return signal to enable an end of cycle for the self-time loop.
