  • Sense amplifier with bit-line derived clocking
    Patent number: 4810910
    Abstract: A sense amplifier device, as of CMOS technology includes a first (AN) and second (AP) amplifier responsive to the voltages (VB0, VB1) of two bit lines (B0, B1) to be amplified. When it is activated, the first amplifier (AN) connects the bit line having the lowest potential to ground potential. When the voltage of one of the bit lines is lower than a threshold voltage (VT), the second amplifier is triggered and connects the bit line having the highest potential to supply voltage.
