  • Reduced swing bit-line apparatus and method
    Patent number: 9947388
    Abstract: Described is an apparatus which comprises: a bit-line (BL) read port; a first local bit-line (LBL) coupled to the BL read port; a second LBL; and one or more clipper devices coupled to the first and second LBLs. The apparatus allows for low swing bit-line to be used for large signal memory arrays. The low swing operation enables reduction in switching dynamic capacitance. The apparatus also describes a split input NAND/NOR gate for bit-line keeper control which achieves lower VMIN, higher noise tolerance, and improved keeper aging mitigation. Described is also an apparatus for low swing write operation which can be enabled at high voltage without degrading the low voltage operation.
