1. A system, comprising:
a memory device; and
a processing device communicatively coupled to the memory device, wherein the processing device is to:
write data to a number of groups of memory cells of the memory device in a physically non-contiguous manner;
track a sequence in which the number of groups of memory cells were written with the data; and
generate, in response to a trigger event, an entry including the tracked sequence to identify at least a portion of the number of groups of memory cells storing data received over a predefined period preceding the trigger event based at least in part on the tracked sequence, wherein the processing device is further to associate, to the entry:
a logical address corresponding to a first page of the at least the portion of the number of groups of memory cells, wherein the first page corresponds to a start time of the predefined period; and
a logical address corresponding to a second page of the at least the portion of the number of groups of memory cells, wherein the second page corresponds to an end time of the predefined period.
