Abstract
A static random access memory unit structure and layout structure includes two pull-up transistors, two pull-down transistors, two slot contact plugs, and two metal-zero interconnects. Each metal-zero interconnect is disposed on each slot contact plug and a gate of each pull-up transistor, in which, each slot contact plug crosses a drain of each pull-down transistor and a drain of each pull-up transistor and extends to cross an end of each metal-zero interconnect. A gap between the slot contact plugs is smaller than a gap between the metal-zero interconnects.
