CORP ACFT PLT CONFUSED AFTER LNDG EVEN WITH PROGRESSIVE TAXI INSTRUCTIONS. CROSSED ACTIVE RWY.

Narrative

WE WERE GIVEN MULTIPLE SPD REDUCTIONS AND TURNS TO ASSIGN FOR THE APCH. FOLLOWING AN LGT WE WERE AT MIN SPACING. THE AIRLINER DID NOT EXIT THE RWY BY THE TIME WE WERE ON SHORT APCH AND THE TWR CTL ISSUED A GAR COMMAND TO US. WE WENT AROUND AND MADE AN UNEVENTFUL LNDG ON 36L; WHILE ALSO OBSERVING ANOTHER AIRLINER BEING ISSUED A GAR ON SHORT APCH TO 36R. AFTER LNDG AND EXITING RWY 36L; I CONTACTED GND CTL AND INFORMED THE CTLR OF MY POS AND INTENTIONS TO PROCEED TO THE FBO ON THE FIELD. I ALSO TOLD THE CTLR I WOULD NEED A PROGRESSIVE TAXI ASSISTANCE; AS THIS WAS THE FIRST TIME I'VE LANDED AT MEM. THE GND CTLR ISSUED INSTRUCTIONS TO MAKE A L TURN ON A TAXIWAY TO INTERSECT TAXIWAY HH AND PROCEEDED E TO TAXIWAY J AND PROCEED NBOUND. UPON REACHING THE INTXN OF THESE TWO TAXIWAYS I OBSERVED AN AIRLINER HOLDING IN POS FOR TKOF ON 36R. IMMEDIATELY STOPPED AS TAXIWAY J CROSSES 36R NBOUND. I VERIFIED THE ROUTING ISSUED BY THE GND CTLR AND HE INDICATED I WAS FOLLOWING CORRECT RTE. AS I PROCEEDED I FOUND MYSELF ON ACTIVE RWY 36R AND IMMEDIATELY EXITED RWY ONTO TAXIWAY CC NBOUND. AT THIS POINT I WAS INSTRUCTED TO PROCEED N ON TAXIWAYS CC TO FBO. UPON ARRIVING AT FBO; I WAS TOLD THE TWR CHIEF DESIRED TO TALK WITH ME. IN OUR CONVERSATION I FULLY EXPLAINED THE INCIDENT IN DETAIL INCLUDING ALL INSTRUCTIONS GIVEN; AND ACTIONS TAKEN BY ME. THE CHIEF INFORMED ME HE WOULD NOT PURSUE THE INCIDENT FURTHER AS NO ACFT WERE ACTUALLY MOVING DURING THE INCURSION.
