Narrative:

I received a complex departure clearance. After copy and readback, I requested segmented taxi instruction. I was proceeding on those instructions and failed to note that the taxiway crossed the active runway until I had entered the runway. Once across, I notified ground of my error. I think the only factor was my preoccupation with understanding the departure clearance. I should have been paying more attention to my present situation, leaving the departure procedure until the aircraft was not moving. No other factors seem relevant.
