This work demonstrates a 256 (row) $ {\times } 512$ (col.) fully row/column-parallel in-memory computing (IMC) macro employing foundry MRAM in 22-nm FD-SOI CMOS.

Row-column addressed (RCA) arrays are 2-D arrays formed by two orthogonal overlapping linear arrays made up of elongated elements. This substantially reduces the number of elements in the 2-D array.
