Stack package including core die stacked over a controller die

1. A stack package comprising:

a core die disposed over a package substrate;

a controller die disposed between the core die and the package substrate to control the core die; and

a bridge die spaced apart from the controller die and disposed between the core die and the package substrate,

wherein the core die comprises:

banks each including memory cell arrays;

an interbank region in which row decoders and column decoders are arranged; and

a pad region in which first connection pads electrically connected to the row decoders and column decoders through first wirings are disposed, and

wherein the controller die comprises:

a through via region in which controller die through vias penetrating the controller die to be connected to the first connection pads are disposed; and

a circuit region in which controlling circuitry electrically connected to the controller die through vias through second wirings is disposed, and

wherein the bridge die electrically connects, without other die intervention, the package substrate to the row decoders and column decoders.

2. The stack package of claim 1 , wherein the core die further comprises second connection pads disposed in the interbank region and electrically connected to the row decoders and column decoders,

wherein the bridge die comprises:

a bridge die body; and

bridge die through vias substantially penetrating the bridge die body to electrically connect the second connection pads to the package substrate.

3. The stack package of claim 2 , wherein the bridge die through vias are disposed at positions vertically overlapped with the second connection pads.

4. The stack package of claim 2 , wherein the bridge die through vias are disposed at positions substantially offset in the horizontal direction from the second connection pads,

wherein the bridge die further comprises redistribution layer patterns electrically connected to the offset bridge die through vias and extending to positions vertically overlapped with the second connection pads.

5. The stack package of claim 4 , wherein each of the redistribution layer patterns extends to connect the plurality of the bridge die through vias to each other so that the plurality of bridge die through vias are electrically connected to one of the second connection pads.

6. The stack package of claim 5 , further comprising inner connectors that electrically connect the second connection pads and the redistribution layer patterns to each other, overlap substantially vertically the second connection pads, and are positioned at positions offset from the bridge die through vias in a substantially horizontal direction.

7. The stack package of claim 1 , wherein the through via region is vertically overlapped with the pad region, and the controller die through vias are disposed to be vertically overlapped with the first connection pads.

8. The stack package of claim 1 , wherein the core die comprises:

two first sides facing each other; and

two second sides facing each other while connecting the first sides,

wherein the pad region extends to connect the first sides while being spaced apart from the second sides, and

wherein the banks and the interbank region are disposed between the pad region and the second sides.

9. The stack package of claim 1 , wherein the controlling circuitry comprises:

at least one command circuit configured for receiving and decoding an external command signal;

at least on address circuit configured for receiving an external address signal; and

at least one input and output circuit.
