Semiconductor packages including chip stacks

1. A semiconductor package comprising:

a first chip stack including first semiconductor chips which are stacked to be offset on a package substrate;

a second chip stack including second semiconductor chips which are stacked to be offset on the package substrate;

a third chip stack including third semiconductor chips which are stacked to be offset and supported by both of the first and second chip stacks;

connectors having first ends which are connected to the first, second, and third semiconductor chips; and

bonding fingers connected to second ends of the connectors opposite to the first ends,

wherein the bonding fingers are arrayed on the package substrate along a first edge of the package substrate, a second edge of the package substrate substantially opposite to the first edge, and a third edge of the package substrate connecting the first edge to the second edge,

wherein the third semiconductor chips are stacked to reveal third bonding pads disposed on the third semiconductor chips;

wherein the bonding fingers includes third bonding fingers disposed between the third edge of the package substrate and the third chip stack to correspond to the third bonding pads;

wherein the third bonding fingers include first sub-bonding fingers and second sub-bonding fingers which are alternately arrayed;

wherein the third chip stack includes:

a first sub-chip stack having some of the third semiconductor chips; and

a second sub-chip stack having the others of the third semiconductor chips which are stacked on the first sub-chip stack; and

wherein the connectors include:

first sub-connectors connecting the first sub-bonding fingers to the first sub-chip stack; and

second sub-connectors connecting the second sub-bonding fingers to the second sub-chip stack.

2. The semiconductor package of claim 1 , wherein the bonding fingers are arrayed along the first, second, and third edges of the package substrate to exhibit a substantially horseshoe-shaped form.

3. The semiconductor package of claim 1 , wherein the bonding fingers include:

first bonding fingers disposed in a region between the first edge of the package substrate and the first chip stack;

second bonding fingers disposed in a region between the second edge of the package substrate and the second chip stack; and

third bonding fingers disposed in a region between the third edge of the package substrate and the third chip stack.

4. The semiconductor package of claim 1 ,

wherein the first semiconductor chips are stacked to reveal first bonding pads disposed on the first semiconductor chips; and

wherein the second semiconductor chips are stacked to reveal second bonding pads disposed on the second semiconductor chips.

5. The semiconductor package of claim 4 , wherein the bonding fingers include:

first bonding fingers disposed between the first edge of the package substrate and the first chip stack to correspond to the first bonding pads; and

second bonding fingers disposed between the second edge of the package substrate and the second chip stack to correspond to the second bonding pads.

6. The semiconductor package of claim 1 , wherein the second sub-connectors include wires which are longer than the first sub-connectors.
