Heat the oven to 350 degrees.
Open one can of crescent roll dough, and press it into the bottom of a well greased 9x13 baking dish.
Blend together the cream cheese, 1 cup of sugar, and salt in a mixing bowl until smooth.
Spread the cream cheese mixture over the dough in the baking dish.
Unroll the second can of dough, and pinch together the seams.
Spread that layer of dough over the filling in the baking dish.
Brush the melted butter over the top.
Combine the remaining sugar with the cinnamon, and sprinkle it over the mixture in the baking dish.
Bake for 30 minutes.
