ABSTRACT:
A sense amplifier is provided which is appropriate for reading memory cells which control N-channel transistors, and which can read single ended registers. The sense amplifier pulls bit and bitbar lines to a high voltage before reading, and interprets equal voltages on two legs as a logical 1. Several embodiments are illustrated, one of which latches the value read from a memory cell, and one of which includes two stages.
