Abstract:
1. A static random access memory (SRAM) cell comprising: first and second inverters cross-coupled for data storage, each inverter including at least one pull-up device and at least two pull-down devices; at least four pass-gate devices configured with the two cross-coupled inverters; at least two ports coupled with the at least four pass-gate devices for reading and writing; a first elongated contact feature extended in a second direction, the first elongated contact feature directly landing on and contacting respective adjacent gates extended, in a first direction perpendicular to the second direction, of the first two pull-down devices (PD-11 and PD-12) of the first inverter; and a second elongated contact feature extended in the second direction, the second elongated contact feature directly landing on and contacting respective adjacent gates extended, in the first direction perpendicular to the second direction, of the second two pull-down devices (PD-21 and PD-22) of the second inverter.
