Sense amplifier with multiple bits sharing a common reference
A memory circuit includes a sense amplifier (10) in which a single reference signal (OUTRFF) is compared to two data signals (OUT1 and OUT2) from two memory cells. The reference signal (OUTRFF) is generated from the combination of memory cells in opposite logic states. The data signal capacitance is...

| Zusammenfassung: | A memory circuit includes a sense amplifier (10) in which a single reference signal (OUTRFF) is compared to two data signals (OUT1 and OUT2) from two memory cells. The reference signal (OUTRFF) is generated from the combination of memory cells in opposite logic states. The data signal capacitance is matched to the reference signal capacitance. With reduced but matched capacitance both high speed and high sensitivity can be achieved. |
