ABSTRACT:
A low power sense amplifier having bit line sensors for sensing the respective voltage levels of a plurality of bit lines, and a latch connected by data lines to the bit lines sensor, for latching the sensed voltage levels. Circuitry of the amplifier prevents formation of a conductive path to ground through both the bit line sensors and the latch when the sensed voltage levels are latched. This provides a sense amplifier which is low in power consumption, while maintaining a relatively high speed, which is particularly useful in CMOS memories.
