Word line coupling prevention using 3D integrated circuit |
摘要 |
A memory comprises a first layer comprising a first line. The memory also comprises second layer comprising a series of bit-cells, a word line driver, and a word line coupled to the word line driver. The memory further comprises a first plurality of through vias coupling the word line to the first line. The word line has a resistance value based on a geometry of the word line, and the first line is configured to reduce the resistance value of the word line by a degree associated with a geometry of the first line. |

1. A memory comprising:
a first layer on a first level, the first layer comprising a first line; a second layer on a second level different from the first level, the second layer comprising:
a series of bit-cells;a word line driver; anda word line coupled to the word line driver; and a first plurality of through vias coupling the word line to the first line, wherein the word line has a resistance value based on a geometry of the word line, and the first line is configured to reduce the resistance value of the word line by a degree associated with a geometry of the first line. |
