Preheat the oven to 375°F. Lightly grease the inside of a 9-inch springform pan. Optional: I also like to place parchment paper on the bottom and the sides for added ease in removing the pie from the pan and keeping the crust intact. Set the pan aside.
In a large food processor, process the graham cracker sheets until they turn into fine crumbles.
Add the melted butter, brown sugar, cinnamon, and salt, and process until well combined.
Press the graham cracker mixture into the prepared springform pan so that the bottom layer is even. You can press some of the mixture to go slightly up the sides around the edge if you like.
Bake at 375°F for 7-10 minutes, until the crust is golden brown.
