Some embodiments include apparatus and methods having dice arranged in a stack. The dice include at least a first die and a second die, and a connection coupled to the dice. The connection may be configured to transfer control information to the first die during an assignment of a first identification to the first die and to transfer the control information from the first die to the second die during an assignment of a second identification to the second die. 1dice arranged in a stack, the dice including at least a first die and a second die; and. An apparatus comprising: This application is a continuation of U.S. application Ser. No. 13/412,367, filed Mar. 5, 2012, which is a continuation of U.S. application Ser. No. 12/209,048, filed Sep. 11, 2008, now issued as U.S. Pat. No. 8,130,527, all of which are incorporated herein by reference in their entirety.Computers and other electronic products, e.g., televisions, digital cameras, and cellular phones, often use memory devices to store data and other information. Some memory devices may have multiple semiconductor dice arranged in a stack. Each of these dice may have its own identification (ID) to allow appropriate communication. Assigning an ID to a die in some conventional techniques may include performing either wire bond programming or fuse programming. Some stacked dice may not have wire bonds, and therefore wire bond programming may be unsuitable. Fuse programming may involve individually assigning an ID to the die before it is arranged in the stack with other dice. Fuse programming may also use some kind of record keeping to track the die and its assigned ID. Record keeping, however, may create additional work.is a block diagram of an apparatus including dice , , , , and , and connections and , according to an embodiment of the invention.
