“…Cryogenic memories have been actively explored for (superconducting) high-performance computing [20], [21], [22], [23], [24], [25] and, more recently, for QC applications. From both perspectives, commercial DRAM memories have been investigated down to 77 K [26], [27], [28], [29], [30], [31]. However, for deep-cryogenic (4.2 K) applications, such as superconducting computing [32], [33], [34], [35], [36], [37], [38], [39] and QC, custom embedded memories have been investigated, including static-cell designs [10], [35], [36], [39], [40], [41], [42] and dynamic-cell designs [32], [43], [44], [45], [46], [47], [48], [49], [50].…”
