a plurality of bond wires coupling the first and second bond pads of the interposer to a lead frame, wherein
the interposer includes a corner, and
the gap includes a portion of the top surface at the corner.
7. The apparatus of claim 6 , wherein the at least one depression is at least one first depression, and wherein the apparatus further comprises:
a second depression in the gap and between the first depression and the first bond pad; and
a third depression in the gap and between the first depression and the second bondpad.
8. The apparatus of claim 6 , wherein the at least one depression has a circular shape.
9. The apparatus of claim 6 , wherein the at least one depression has an L shape.
10. The apparatus of claim 6 , wherein the at least one depression comprises a plurality of square-shaped depressions.
11. The apparatus of claim 6 , wherein the interposer further includes at least one other depression at the top surface of the interposer, and wherein the encapsulant material is disposed in the other depression.
12. A system comprising:
a flash memory device including an interposer including
at least one first depression at an edge of the interposer, wherein the first depression is in a side surface of the interposer, and wherein the side surface is adjacent a top surface of the interposer, and
at least one second depression between individual bond pads of the interposer;
a die coupled to the top surface of the interposer; and
an encapsulant material formed over the die and the interposer, and disposed in the first and second depressions to resist movement of the encapsulant material relative to the interposer;
a host logic device; and
a host logic device bus coupled with the phase change memory device and the host logic device.
13. The system of claim 12 , wherein the flash memory device comprises phase change memory device.
14. The system of claim 12 , wherein the host logic device includes a plurality of processor cores.
15. The system of claim 12 , wherein the system is a selected one of a set-top box, a digital reorder, a game console, a personal digital assistant, a mobile phone, a digital media player, or a digital camera.
16. An apparatus comprising:
an interposer having a surface, at least one corner, a first peripheral edge at the corner, and a second peripheral edge at the corner, the interposer including
a first bond pad adjacent the first peripheral edge,
a second bond pad adjacent the second peripheral edge and separated from the first bond pad by a portion of the surface between the first and second bond pads, and
at least one depression in the portion of the surface of the interposer;
a die attached to the surface of the interposer; and
