ABSTRACT:
A memory cell comprising a storage cell and a comparison circuit. The storage cell has a second node and a third node. The comparison circuit is coupled to the storage cell and comprises a first plurality of transistors coupled in series to a first input and a second plurality of transistors coupled in series to a second input and coupled to the first plurality of transistors by a first node and by a source voltage node. A match line coupled to the first node indicates a miss when values on the first and second inputs are different than values stored in the storage cell.
