Abstract
Respective die IDs are determined for a plurality of memory die commonly packaged as a memory device based on their respective Unique Identifiers ('UIDs'). An external controller initiates an internal Die ID ('DID') determination process in which each die eventually asserts a signal on its inter-die signaling pin after a number of clocks as determined by its UID, and assigns itself a Die ID based on the number of signals asserted by other die prior to its own signaling response. Each die keeps track of the number of signals asserted by the other die prior to its own signaling response, as well as, optionally, the total number of signals on the signaling pin to determine the package die count for the device.
