A Benchmark of Cryo-CMOS 40-nm Embedded SRAM/DRAMs for Quantum Computing

The cryogenic electronic interface for quantum pro-cessors requires cryo-CMOS embedded memories that cover a wide range of specifications. The temperature dependence of device parameters, such as the threshold voltage, the gate/subthreshold leakage, and the variability, severely alters the memories' performance between room temperature (RT)...
