  • Patent number: 10984855
    Abstract: Methods and systems to provide a multi-Vcc environment, such as to selectively boost an operating voltage of a logic block and/or provide a level-shifted control to the logic block. A multi-Vcc environment may be implemented to isolate a Vmin-limiting logic block from a single-Vcc environment, such as to reduce Vmin and/or improve energy efficiency in the single-Vcc environment. The logic block may include bit cells of a register file, a low-level processor cache, and/or other memory system. A cell Vcc may be boosted during a read mode and/or write wordlines (WWLs) and/or read wordlines (RWLs) may be asserted with boost. A wordline decoder may include a voltage level shifter with differential split-level logic, and a dynamic NAND, which may include NAND logic, a keeper circuit, and logic to delay a keeper control based on a delay of the level shifter to reduce contention during an initial NAND evaluation phase.

  • 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.
