A trench memory filled with a monolithic conducting material and methods for forming the same are disclosed. The trench memory includes a trench that has only a single, monolithic conducting material within the trench. The method includes forming a trench with a collar in the trench; forming a node dielectric on a sidewall of the trench; and filling the trench with a monolithic conducting material, such as polysilicon.
