  • Multi-phase clock monitor circuit
    Patent number: 4117348
    Abstract: A test circuit to continuously monitor both narrow width (.phi..sub.1 and .phi..sub.3) and wide width (.phi..sub.1+2 and .phi..sub.3+4) multi-phase clocks for proper toggling or switching. If any one of the clocks fails to toggle (i.e. remains at a constant output voltage level) or if either of the .phi..sub.1 and .phi..sub.3 or .phi..sub.1+2 and .phi..sub.3+4 clocks are on at the same time, the circuit provides a corresponding output signal, which signal is indicative of a clock failure.

  • Memory clocking system
    Patent number: 3943496
    Abstract: A solid state memory employs a plurality of memory cells each capable of storing either of two different binary values. The memory cells require periodic application of a refresh pulse to the memory cell to, without rewriting, enhance at least one of the two different binary values which the memory cells can store, in order to prevent loss of that binary value over a period of time. The reliability of the memory is improved by supplying a refresh signal which includes a plurality of refresh pulses in each memory cycle.
