A sense amplifier circuit for sensing a logic state of a selected memory
cell in a memory circuit includes a precharge circuit and a latch
circuit. The precharge circuit is adapted for connection to a pair of
complementary bit lines corresponding to the selected memory cell and is
operative to selectively drive the pair of complementary bit lines to a
first voltage in response to a first control signal. The latch circuit is
adapted for connection to the pair of complementary bit lines. The sense
amplifier circuit further includes a replication circuit adapted for
connection to the pair of complementary bit lines. The replication
circuit is operative to selectively transfer a voltage representative of
a logic state on a first bit line of the pair of complementary bit lines
to a second bit line of the pair of complementary bit lines in response
to at least a second control signal.
