Abstract:
A system and method for performing three scans for testing an address decoder and word line drive circuits is disclosed. The first scan determines whether only one word line is selected. The second scan determines whether the word line rise time to a target voltage level is within a specified time. Finally, the third scan determines whether the correct word line was selected.
