主权项

1. An apparatus comprising:
a stack of dice comprising a first die having a control circuit and a monitor circuit, and a second die having an identification (ID) circuit, wherein the ID circuit of the second die is configured to determine ID information associated with the second die, and wherein the control circuit of the first die is configured to detect the second die by comparing a monitored current at the monitor circuit of the first die with a reference current determined by a resistance of the ID circuit of the second die.
