Abstract
This specification describes an associative memory cell capable of performing logic functions. The cell comprises two transistors with their collectors connected to an output line; with their emitters either left floating or connected to an input line carrying either true or complement of one variable; and with their bases either connected to an input line carrying the true or complement of a second variable or to the output line which is maintained at a fixed potential. This permits the performing of sixteen different logic functions of the two input variables by the cell.
