A new hybrid current-mode sense amplifier for fast CMOS SRAMs is presented. The sensing speed is twice that of the conventional current-sensing data path and independent of the bit-line and data-line capacitances. In addition, low voltage swings at bit lines and data lines reduce the power dissipation and voltage noise coupling significantly.
