  • Semiconductor memory with improved power supply control circuit
    Patent number: 5420823
    Abstract: A semiconductor memory has sense amplifiers which are supplied with a first potential from a first supply line and a second potential from a second supply line. A switching element on the first supply line is controlled by the potential of the second supply line, its conductivity increasing as the potential of the second supply line moves toward the second potential. A similar switching element, controlled by the potential of the first supply line, can be provided on the second supply line.
