Abstract

A wafer includes a group of tiles of programmable logic formed thereon, wherein each tile comprises a micro control unit (MCU) communicating with adjacent MCUs, and wherein each MCU is controlled in a predetermined order of priority by adjacent MCUs; and dice lines on the wafer to separate the group into one or more end-devices.

Claims (26)

1. A wafer, comprising:

a group of tiles of programmable logic formed thereon, wherein each tile comprises a micro control unit (MCU) communicating with adjacent MCUs on one layer to configure the group of tiles, and wherein each MCU is controlled in a predetermined order of priority by adjacent MCUs, where each MCU comprises a processor and memory, and where the MCUs control and initialize the programmable logic; and

dice lines on the wafer to separate the group into a plurality end-devices.

2. The wafer of claim 1 , wherein the dice lines separate the wafer into various die sizes.

3. The wafer of claim 1 , comprising one or more dies coupled to the tiles using Through Silicon Vias.

4. The wafer of claim 1 , wherein the dies are logic dies, comprising dedicated masks coupled to unused dice lines to connect individual tiles according to a desired die size.

5. The wafer of claim 1 , wherein the programmable logic comprises field programmable gate array (FPGA).

6. The wafer of claim 1 , wherein the programmable logic comprises field programmable gate array (FPGA) and wherein the MCU loads the FPGA with programmed function and initialize the FPGA.

7. The wafer of claim 1 , wherein an adjacent MCU is controlled by a west MCU if one exists, and if not, by a south MCU.

8. The wafer of claim 1 , wherein the control inputs to one MCU are used to control the end-device and spread to other tiles.

9. The wafer of claim 1 , wherein the MCUs are utilized for user functions during end-device operation after the end-device has completed set up or initialization.

10. The wafer of claim 1 , comprise Input/Output (I/O) circuit connected to it by Through Silicon Via (TSV).

11. A semiconductor device, comprising;

a first mono-crystallized semiconductor layer; and

a second mono-crystallized semiconductor layer;

wherein said first and second mono-crystallized semiconductor layers are overlaying one on top of the other, and

wherein said second mono-crystallized semiconductor layer comprise repeating memory structure with sub structures defined by etching as a customization step after the repeating memory structure had been fabricated.

12. The device according to claim 11 , wherein said second mono-crystallized semiconductor layer comprises logic circuits, wherein said logic circuit communicates with an external device through I/O circuits constructed on a third mono-crystallized semiconductor layer.

13. The device according to claim 11 comprising a third mono-crystallized semiconductor layer, wherein said third mono-crystallized semiconductor layer comprise I/O circuits.

14. The device according to claim 12 , wherein said I/O circuits comprise Through Silicon Via (TSV).

15. The device according to claim 11 , wherein said second mono-crystallized semiconductor layer comprises programmable logic circuits.

16. The device according to claim 11 , wherein said second mono-crystallized semiconductor layer comprises gate-array.

17. The device according to claim 13 , comprising processing a memory structure on a different line than said I/O circuits.

18. The device according to claim 11 , wherein said device is used in a mobile system.

19. The device according to claim 11 , comprising one or more masks used to construct said device are used to fabricate another device.

20. The device according to claim 11 , wherein the layer is etched to form dice lines.
