Abstract

A sense amplifier includes a cross latch, a first pass gate, a second pass gate, a first data line, a second data line, a first circuit, and a second circuit. The cross latch has a first input/output (I/O) node and a second I/O node. The first pass gate is coupled between the first data line and the first I/O node. The second pass gate is coupled between the second data line and the second I/O node. The first circuit is coupled with the first I/O node and the second data line. The second circuit is coupled with the second I/O node and the first data line. The first circuit is configured to be turned off when the second data line has a first logical value and to be at least lightly turned on when the second data line has a voltage level between the first logical value and a second logical value different from the first logical value. The second circuit is configured to be turned off when the first data line has the first logical value and to be at least lightly turned on when the first data line has a voltage level between the first logical value and the second logical value.
