determining that a timer is active; and

responsive to determining that the timer is active, tracing the third read request.

add a record to the table for the traced third read request including the second region, a sequence number assigned to the third read request, and the second length.

14 . The non-transitory computer-readable storage medium of claim 8 , wherein the processing device is further to:

receive a third read request during the second boot time;

determine that a timer is active; and

responsive to determining that the timer is active, trace the third read request.

15 . A system comprising:

a plurality of memory devices; and
