SRAM cells with Vth-controllable independent double-gate (IDG) FinFETs have been successfully fabricated. The performance of the fabricated SRAM cell with various circuit topologies has been investigated comprehensively. Both a reduction of leakage current and an enhancement of read and write noise margins have been successfully demonstrated by introducing the IDG FinFETs into the SRAM cells.
