A nonvolatile memory embedded in an advanced logic circuit and a method forming the same are provided. In the nonvolatile memory, the word lines and erase gates have top surfaces lower than the top surfaces of the control gate. In addition, the word lines and the erase gates are surrounded by dielectric material before a self-aligned silicidation process is performed. Therefore, no metal silicide can be formed on the word lines and the erase gate to produce problems of short circuit and current leakage in a later chemical mechanical polishing process.
