A memory stack includes a number of memory dies including a master die and one or more slave dies. The slave die can be converted to a master die by further processing. The slave die includes a memory core having memory cell arrays. The slave die also includes first and second metal layers that form first and second distribution lines in the memory core, respectively. An interface circuit in the slave die is decoupled from the first and second metal layers.
