The effects of Memnarch’s abilities don’t end at end of turn, and they don’t end when Memnarch leaves the battlefield. Both effects last until the affected permanent leaves the battlefield.

You can use the first ability on a nonartifact permanent, wait for the ability to resolve, and then use the second ability on that permanent.
