Inflight Event / Encounter Wake Vortex Encounter
General None Reported / Taken
Environment - Non Weather Related
We were on a visual approach to MEM 36L behind a B777 approximately 4 miles in trail. While on the glideslope to 36L between 1;000 to 1;500 FT we [encountered] the wake of the preceding B777. Our Aircraft banked approximately 15 degrees right; then left; followed by a tail windshear warning then a head windshear warning. We executed a go-around followed by a normal landing. I am certain the windshear was the result of the significant wake turbulence from the B777.
Widebody Captain reported wake vortex encounter in trail of a B777 on approach to MEM.
