Abstract
A layout pattern of a static random access memory (SRAM) preferably includes a first inverter and a second inverter. Preferably, the first inverter includes a first gate structure extending along a first direction on a substrate, in which the first gate structure includes a gate of a first pull-up device (PL) and a gate of a first pull-down device (PD). The second inverter includes a second gate structure extending along the first direction on the substrate, in which the second gate structure includes a gate of a second pull-up device (PL) and a gate of a second pull-down device (PD) and the gate of the PDis directly under the gate of the PD
