Patent number: 8885423Abstract: The disclosed embodiments provide a sense amplifier for a dynamic random-access memory (DRAM). This sense amplifier includes a bit line to be coupled to a cell to be sensed in the DRAM, and a complement bit line which carries a complement of a signal on the bit line.
