Since most flat slabs contain reinforcing steel, the minimum would be the thickness required to cover the steel, generally 2" top and bottom. But the real answer depends on what the slab is supporting and the level of safety required. For a very general situation where the slab is supported on all sides and not significantly longer in one direction, a slab can be 6" wide and support light loading if properly reinforced.
The minimum covering of reinforcement for roof slab is 30mm

The minimum area of steel required in RCC slab as per BS code is 0.12 to 0.15% of total area. The maximum diameter of bar in slab, shall not exceed D/8, where D is the total thickness of slab.
