Ground cleared me to taxi from the main/passenger ramp to the north ramp via alpha hold at 32. The active in use was 23 and as I was being given the clearance I was watching the activity on 23. I taxied on alpha and crossed 32. The controller called my attention to the fact that I had crossed 32 after being told to hold at 32. My response was that I had heard him say 32, but had transposed 23 and 32 in my mind as I taxied. After this incident I have begun writing down even simple ground instructions so as to be able to have something better than memory and similar runway numbers for reminding me.
