Abstract:
An electronic device includes a die stack having a plurality of die. The die stack includes a die parity path spanning the plurality of die and configured to alternatingly identify each die as a first type or a second type. The die stack further includes an inter-die signal path spanning the plurality of die and configured to propagate an inter-die signal through the plurality of die, wherein the inter-die signal path is configured to invert a logic state of the inter-die signal between each die. Each die of the plurality of die includes signal formatting logic configured to selectively invert a logic state of the inter-die signal before providing it to other circuitry of the die responsive to whether the die is designated as the first type or the second type.
