Abstract: Systems and methods relate to memory operations in a memory array. A compare operation is performed using a sense amplifier. True and complement versions of a search bit are compared with true and complement versions of a data bit stored in a data row of the memory array to generate true and complement sense amplifier inputs. The true and complement sense amplifier inputs are amplified in the sense amplifier to generate a single-ended match signal. The single-ended match signal can be aggregated with other single-ended match signals in the data row to determine whether there is a hit or miss for a compare operation on the entire data row.
