Classification: CPC H | IPC H

Claim 14:
15. A static random access memory (SRAM) cell comprising:
two pull-up (PU) transistors;
two pull-down (PD) transistors; and
two pass-gate (PG) transistors above the PU transistors, wherein the PU transistors and the PD transistors are configured to form two cross-coupled inverters, the PG transistors are electrically connected to the cross-coupled inverters, one of the PU transistors and one of the PD transistors are horizontal-gate-all-around (HGAA) transistors, and one of the PG transistors is a vertical-gate-all-around (VGAA) transistor.
