Abstract:
A Static Random Access Memory (SRAM) cell includes a first pull-up transistor and a second pull-up transistor, and a first pull-down transistor and a second pull-down transistor forming cross-latched inverters with the first pull-up transistor and the second pull-up transistor. A conductive feature includes a first leg having a first longitudinal direction, wherein the first leg interconnects a drain of the first pull-up transistor and a drain of the first pull-down transistor. The conductive feature further includes a second leg having a second extending direction. The first longitudinal direction and the second extending direction are un-perpendicular and un-parallel to each other. The second leg interconnects the drain of the first pull-up transistor and a gate of the second pull-up transistor.
