Abstract
A semiconductor comprising a plurality of first building blocks arranged in one or more first rows and a plurality of second building blocks arranged in one or more second rows. The one or more second rows are interleaved with the one or more first rows and the first building blocks and the second building blocks each provide a segment of horizontal and a segment of vertical routing.
Claims19
A semiconductor comprising:
- a plurality of first building blocks arranged in one or more first rows, each of said first building blocks having a first layer, a second layer and a third layer, said first layer having a first metal portion and a second metal portion, said first metal portion being larger than said second metal portion;
- and
- a plurality of second building blocks arranged in one or more second rows, each of said second building blocks having a first layer, a second layer and a third layer, said first layer of said second building blocks having a first metal portion and a second metal portion, said first metal portion being larger than said second metal portion, wherein (i) said first metal portion and said second metal portion in said first layer of said second building blocks are arranged complementary to said first metal portion and said second metal portion in said first layer of said first building blocks, (ii) said one or more second rows are interleaved with said one or more first rows and (iii) said first building blocks and said second building blocks each provide a single segment of horizontal routing and a single segment of vertical routing.
A semiconductor comprising:
- means for programming one or more first vertical segments and one or more first horizontal segments arranged in one or more first rows;
- and
- means for programming one or more second vertical segments and one or more second horizontal segments arranged in one or more second rows, wherein (i) a first layer of each of said means for programming one or more first vertical segments and one or more first horizontal segments and said means for programming one or more second vertical segments and one or more second horizontal segments has a first metal portion and a second metal portion, said first metal portions being larger than said second metal portions, (ii) said first metal portion and said second metal portion of said means for programming one or more second vertical segments and one or more second horizontal segments are arranged complementary to said first metal portion and said second metal portion of said first layer of said means for programming one or more first vertical segments and one or more first horizontal segments, and (iii) said one or more second rows are interleaved with said one or more first rows.
