Abstract
Some embodiments include apparatuses and methods having multiple decks of memory cells and associated control gates. A method includes forming a first deck having alternating conductor materials and dielectric materials and a hole containing materials extending through the conductor materials and the dielectric materials. The methods can also include forming a sacrificial material in an enlarged portion of the hole and forming a second deck of memory cells over the first deck. Additional apparatuses and methods are described.
