1. A system comprising:
a memory device; and
a processing device, operatively coupled with the memory device, configured to perform operations comprising:
detecting an asynchronous power loss event at the memory device; and
in response to detecting the asynchronous power loss event, performing an asynchronous power loss recovery process, the performing of the asynchronous power loss recovery process comprising determining whether to write dummy data to a last written page based on a number of zeroes programmed in the last written page.
