Doomsday was created out of a series of clones that had their DNA adjusted to be immune to their previous cause of death. This artificial evolution reached a level to where the cells could reanimate themselves.

Technically if all of his cells were destroyed, Doomsday could theoretically die. However Imperiex was unable to 100% kill Doomsday despite being 'as powerful as the big bang': and other gods have been unable to kill Doomsday too.

The only method to kill Doomsday for good is to erase him or everything from existence; like sending him to the end of time.
