Narrative:
Working moderate level traffic with several inbounds. Descended one arrival to go under a memphis departure. When it looked like we would need turns to help separation, I turned the arrival to go north of the departure. The arrival descended through the airspace of another aircraft wbound at FL220, which I was not aware of until the conflict alert activated. I had the aircraft expedite his descent to miss the level aircraft. Supplemental information from acn 632662: aircraft #1 was descending into memphis. Aircraft #2 was level at FL220 also landing mem. Aircraft #1 was turned to miss departing aircraft from mem, the aircraft was turned into aircraft #2.
Original NASA ASRS Text
Title: A ZME ARTCC RADAR CTLR WHILE VECTORING ARR TFC LNDG MEM IS UNABLE TO MAINTAIN PROPER SEPARATION FROM A SECOND ACFT LNDG MEM.
Narrative: WORKING MODERATE LEVEL TFC WITH SEVERAL INBOUNDS. DSNDED ONE ARR TO GO UNDER A MEMPHIS DEP. WHEN IT LOOKED LIKE WE WOULD NEED TURNS TO HELP SEPARATION, I TURNED THE ARR TO GO N OF THE DEP. THE ARR DSNDED THROUGH THE AIRSPACE OF ANOTHER ACFT WBOUND AT FL220, WHICH I WAS NOT AWARE OF UNTIL THE CONFLICT ALERT ACTIVATED. I HAD THE ACFT EXPEDITE HIS DSCNT TO MISS THE LEVEL ACFT. SUPPLEMENTAL INFO FROM ACN 632662: ACFT #1 WAS DSNDING INTO MEMPHIS. ACFT #2 WAS LEVEL AT FL220 ALSO LNDG MEM. ACFT #1 WAS TURNED TO MISS DEPARTING ACFT FROM MEM, THE ACFT WAS TURNED INTO ACFT #2.
