A current sensing read arrangement for a static random access memory in which critical nodes in the sensing arrangement are equalised before read-out commences, and in which differential outputs are applied to a gating arrangement which terminates the read-out as soon as a recognisable output signal is obtained, so as to minimise power consumption.

Random access memory

A programmable logic cell has two inputs and six outputs, each output being a different logical function of the inputs. Each output is generated by a pair of NMOS transistors, one transistor of each pair having its gate connected to one of the inputs and the other transistor of each pair having its gate connected to the inverse of the same input.

Logic cell using only two N type transistors for generating each logic

A transponder tag operative in the UHF range and including a substrate of dielectric material having formed on one side a conductive surface providing a ground plane and a dipole antenna, a slot line within the ground plane forming a balanced antenna feeder and leading to the center of the dipole antenna, and the substrate having mounted on the side of the substrate opposite to the one side a transmission line feeder positioned for electromagnetic coupling with the slot line, the transmission line feeder being coupled to transceiver circuit and processing circuit mounted on the opposite side for performing a transponding function.
