Patent ReferencesUse of voltage equalization in signal-sensing circuits Latch type sense amplifier having a negative feedback device Apparatus for a semiconductor memory with independent reference voltage Sense amplifier with independent write-back capability for ferroelectric random-access memories Patent #: 6563753 InventorsAssigneeApplicationNo. 10295718 filed on 11/15/2002US Classes:365/205, Flip-flop used for sensing365/145, Ferroelectric365/149, Capacitors365/189.09, Including reference or bias voltage generator365/208, Semiconductors365/207Differential sensingExaminersPrimary: Ho, HoaiAttorney, Agent or FirmInternational ClassG11C007/00AbstractAn integrated circuit memory device can include a memory cell circuit configured to store data and a sense amplifier circuit configured to sense and amplify the stored data provided as a first input to the sense amplifier circuit in comparison to a reference voltage provided as a second input to the sense amplifier circuit. A bit line electrically can be coupled to the memory cell circuit and indirectly electrically coupled to the first input of the sense amplifier circuit and configured to provide the stored data to the sense amplifier circuit. A reference voltage line can also be indirectly electrically coupled to the second input of the sense amplifier circuit and configured to provide the reference voltage to the sense amplifier circuit. | |
