Narrative:
During approach to runway 36C mem, level at 2000 ft, 170 KIAS, at approximately 10 DME, ATC advised of traffic ahead and below flight path which was below the class B airspace. Moments later, we visually acquired the traffic and on TCASII, which showed the traffic to be 400 ft below us. We then received an RA on the TCASII. A slight climb was initiated of less than 200 ft until TCASII called clear of traffic. Completed an uneventful approach to landing.

Narrative: DURING APCH TO RWY 36C MEM, LEVEL AT 2000 FT, 170 KIAS, AT APPROX 10 DME, ATC ADVISED OF TFC AHEAD AND BELOW FLT PATH WHICH WAS BELOW THE CLASS B AIRSPACE. MOMENTS LATER, WE VISUALLY ACQUIRED THE TFC AND ON TCASII, WHICH SHOWED THE TFC TO BE 400 FT BELOW US. WE THEN RECEIVED AN RA ON THE TCASII. A SLIGHT CLB WAS INITIATED OF LESS THAN 200 FT UNTIL TCASII CALLED CLR OF TFC. COMPLETED AN UNEVENTFUL APCH TO LNDG.
