GATED-FEEDBACK SENSE AMPLIFIER FOR SINGLE-ENDED LOCAL BIT-LINE MEMORIES

A single-ended input sense amplifier uses a pass device to couple the input local bit-line to a global bit-line evaluation node. The sense amplifier also includes a pair of cross-coupled inverters, a first inverter of which has an input that coupled directly to the global bit-line evaluation node. T...

Summary:A single-ended input sense amplifier uses a pass device to couple the input local bit-line to a global bit-line evaluation node. The sense amplifier also includes a pair of cross-coupled inverters, a first inverter of which has an input that coupled directly to the global bit-line evaluation node. The output of the second inverter is selectively coupled to the global bit-line evaluation node in response to a control signal, so that when the pass device is active, the local bit line charges or discharges the global bit-line evaluation node without being affected substantially by a state of the output of the second inverter. When the control signal is in the other state, the cross-coupled inverter forms a latch. An internal output control circuit of the second inverter interrupts the feedback provided by the second inverter in response to the control signal.
