Abstract: An on-die logic analyzer (ODLA) can reduce the time and resources that would otherwise be spent in validating or debugging memory system timings. The ODLA can receive an enable signal with respect to a start command and start a count of clock cycles in response to a first issued command matching the start command defined in a first mode register. The ODLA can stop the count of clock cycles in response to a second issued command matching a stop command defined in a second mode register. The ODLA can write a value indicative of the stopped count to a third mode register or an on-die storage array in response to the stopped count exceeding a previously stored count.
