HARDWARE LATENCY MONITORING FOR MEMORY DEVICE INPUT/OUTPUT REQUESTS

A system includes a hardware circuitry having a device coupled with one or more external memory devices. The device is to detect an input/output (I/O) request associated with an external memory device of the one or more external memory devices. The device is to record a first timestamp in response to detecting the I/O request transmitted to the external memory device. The device is further to detect an indication from the external memory device of a completion of the I/O request associated with the external memory device and record a second timestamp in response to detecting the indication. The device is also to determine a latency associated with the I/O request based on the first timestamp and the second timestamp.
