Die-to-Die Power Delivery
A die includes one or more power delivery layers to deliver power within the die. Additionally, the die also includes one or more transistor layers to at least partially implement a programmable fabric for the die. Furthermore, the die further includes one or more signal routing layers to transmit signals for use by the programmable fabric. Moreover, the one or more transistor layers physically separate the one or more power delivery layers from the one or more signal routing layers.

a first die; and
a second die coupled to the first die, wherein the second die comprises:
one or more power delivery layers to deliver power within the second die, to deliver die-to-die signals to and from the first die, and to deliver clock delivery;
one or more transistor layers to at least partially implement a programmable fabric for the die; and
one or more signal routing layers to transmit signals for use by the programmable fabric, wherein the one or more transistor layers physically separate the one or more power delivery layers from the one or more signal routing layers.

4 . The system of claim 3 , wherein a second portion of the bumps are coupled to the interconnect and to a fabric portion of the second die.
5 . The system of claim 1 , wherein the one or more power delivery layers are on a first side of the second die.
6 . The system of claim 5 , wherein the one or more signal routing layers are on a second side of the second die that is opposite to the first side.
7 . The system of claim 6 , wherein the first side is a bottom side of the second die, and the second side is a top side of the second die.
8 . The system of claim 1 , wherein the one or more signal routing layers and the one or more power delivery layers are vertically separated and parallel to each other.
9 . A package, comprising:
an interconnect;
a first die; and
