1. A memory sub-system comprising:
a clock to provide a clock signal;
a memory device; and
a processing device, operatively coupled with the memory device, to perform operations comprising:
receiving, from a host system, a command to arm the memory device for self-destruction;
in response to the command, commencing a self-destruction countdown timer, the commencing of the self-destruction countdown timer comprising using the clock signal provided by the clock to track a total elapsed time since receiving the command;
detecting expiry of the self-destruction countdown timer; and
based on detecting the expiry of the self-destruction countdown timer, destructing data stored by the memory device.
