Narrative:
En route, approximately 20 mi north of memphis, received clearance to go to '350' then direct stl. Interpreted clearance to climb to FL350 when controller meant a heading of 350 degrees. Out of FL334, the controller queried as to why we were off our assigned altitude of FL330. We returned to FL330 without further incident or apparent traffic conflict.
