Structured integrated circuit device
View Patent ↗A configurable logic array may include: a multiplicity of logic cells, containing look-up tables; customizable metal and via connection layers overlying the multiplicity of logic cells; a multiplicity of device customizable I/O cells; a multiplicity of configuration customizable RAM blocks; a ROM block with customizable contents; and a microprocessor with customizable I/O for configuring and testing the array, where the customizations are all done on a single via layer.
1. A semiconductor device comprising:
a logic array, said logic array including blocks of logic cells;
metal and via connection layers overlying the blocks of logic cells for providing at least one permanent customized interconnect between various inputs and outputs thereof;
wherein said permanent customized interconnect is customized by a single custom via layer and wherein said permanent customized interconnect includes at least one interconnection to distribute power to at least one of said blocks of logic cells.
2. A semiconductor device as in claim 1 , wherein said at least one interconnection to distribute power to at least one of said blocks of logic cells is customized to connect at least one of said blocks to ground.
