Abstract
A method for generating a unique device ID for each addressable device in a stack of multiple addressable devices by encoding a device ID for one device in the stack and determining a device ID for each of the other devices based on the device ID of an adjacent device in the stack.
Claims43
An apparatus comprising:
- a first addressable device associated with a first device identifier (ID);
- a second addressable device stacked adjacent to the first addressable device, wherein the second addressable device is coupled to the first addressable device and includes a circuit to generate a second device ID as a function of the first device ID.
An apparatus comprising:
- a first addressable device having a first device ID;
- a second addressable device stacked on the first addressable device,
- wherein the second addressable device is coupled to the first addressable device and includes means for generating a second device ID as a function of the first device ID.
An apparatus comprising:
- a first integrated circuit die and a second integrated circuit die in a stacked configuration, the first integrated circuit die including:
- a through-silicon via;
- and
- a device identification (ID) generating circuit, the device ID
- generating circuit to receive a first device ID and to provide a
- second, different device ID that is a function of the first device ID,
- the second device ID to identify the second integrated circuit die.
