    Abstract: Digital compute-in-memory (DCIM) bit cell circuit layouts and DCIM array circuits for multiple operations per column are disclosed. A DCIM bit cell array circuit including DCIM bit cell circuits comprising exemplary DCIM bit cell circuit layouts disposed in columns is configured to evaluate the results of multiple multiply operations per clock cycle. The DCIM bit cell circuits in the DCIM bit cell circuit layouts each couples to one of a plurality of column output lines in a column. In this regard, in each cycle of a system clock, each of the plurality of column output lines receives a result of a multiply operation of a DCIM bit cell circuit coupled to the column output line. The DCIM bit cell array circuit includes digital sense amplifiers coupled to each of the plurality of column output lines to reliably evaluate a result of a plurality of multiply operations per cycle.

    Abstract: A fin-based structure may include fins on a surface of a semiconductor substrate. Each of the fins may include a doped portion proximate to the surface of the semiconductor substrate. The fin-based structure may also include an isolation layer disposed between the fins and on the surface of the semiconductor substrate. The fin-based structure may also include a recessed isolation liner on sidewalls of the doped portion of the fins. An unlined doped portion of the fins may extend from the recessed isolation liner to an active portion of the fins at a surface of the isolation layer. The isolation layer is disposed on the unlined doped portion of the fins.
