Narrative:

Departing rdu, we leveled off at 17000 ft. I was checking my charts for the next fix when ATC cleared us to climb to FL230. I responded and set 230 in the altitude alerter then went back to checking my chart. The captain responded to the altitude properly. We did not immediately begin the climb, though. The captain was checking the radar and I was in my chart. We allowed ourselves to be distracted and stayed at 17000 ft for about 3 mins when ATC asked our altitude. We then realized our error and climbed to FL230.
