发明名称 SRAM cells suitable for Fin field-effect transistor (FinFET) process
摘要 A static random access memory (SRAM) cell includes first and second n-channel transistors, first and second p-channel transistors, first and second enable transistors, and first and second pass gates. The first n-channel transistor, the first p-channel transistor, and the first enable transistor are connected in series between first and second reference potentials. The second n-channel transistor, the second p-channel transistor, and the second enable transistor are connected in series between the first and second reference potentials. The first pass gate is configured to selectively connect a first bitline to a first node. The first node is connected to a gate of the first n-channel transistor and a gate of the first p-channel transistor. The second pass gate is configured to selectively connect a second bitline to a second node. The second node is connected to a gate of the second n-channel transistor and a gate of the second p-channel transistor.
