  • Bi-directional sense amplifier stage for memory datapath
    Patent number: 6275435
    Abstract: A sense amplifier (SA) stage includes a single SA used to selectively sense signals from both directions in a datapath. The SA is connected to detect the differential signal present at a pair of sense nodes on the datapath. A first pair of switches is inserted in the datapath between the sense nodes and a first transfer port (FTP). A first equalizer is connected to the differential lines at points between the first pair of switches and the FTP. A second pair of switches is inserted in the datapath between the sense nodes and a second transfer port (STP), with a second equalizer connected to the differential lines between the second pair of switches and the STP. Before transferring data from the FTP to the STP, the first equalizer is turned on while the first pair of switches is turned off. While the data is being developed at the FTP, the first equalizer is turned off, the first pair of switches is turned on, the second pair of switches is off, and the second equalizer is on.
