SEMICONDUCTOR MEMORY DEVICE HAVING SENSE AMPLIFIER |
摘要 |
A sense amplifier prevents a reduction in sensing margin occurring when data forms an island pattern. The sense amplifier includes a first inverter having an input terminal connected to a bit line and an output terminal connected to a bar bit line, and a second inverter having an input terminal connected to the bar bit line and an output terminal connected to the bit line. The first and second inverters are configured to receive a pull-up voltage through different pull-up voltage lines, respectively.
