  • Patent number: 5594695
    Abstract: The present invention relates to a semiconductor memory device having a sense amplifier operated by a given control signal and a sense amplifier driver. A comparator compares the amplified sense amplifier driver with a reference voltage. A comparison output signal is enabled and used by a bias circuit and a sense amplifier driver control circuit, which circuit has an output line connected to a control terminal of the sense amplifier driver. The output line signal variably controls current flowing into the sense amplifier driver by allowing the amount of current to be increased when transmitting data from a RAM port to a SAM port. A bias circuit maintains the current flowing into the driving element at a constant state regardless of an increment or decrement of an external power supply voltage.

  • Patent number: 5572475
    Abstract: The present invention relates to a semiconductor memory device and more particularly to a sense amplifier control circuit capable of stabilizing memory cell voltage characteristics by clamping an external power supply voltage to an internal power supply voltage. The semiconductor memory device according to the present invention has a sense amplifier operated by a given control signal and a first sense amplifier driver. A sense amplifier driver control circuit has an output line connected to a control terminal of the first sense amplifier driver for variably controlling current flowing into the first sense amplifier driver by allowing the amount of current to be increased when transmitting data from a RAM port to a SAM port. A bias circuit has an output line connected to a control terminal of a driving element of the sense amplifier driver control unit and maintains the current flowing into the driving element at a constant state regardless of an increment or decrement of an external power supply voltage.
