In some embodiments related to reading data in a memory cell, the data is driven to a local bit line, which drives a local sense amplifier. Depending on the logic level of the data in the memory cell and thus the local bit line, the local sense amplifier transfers the data on the local bit line to a global bit line. A neighbor global bit line is used as a reference for a global sense amplifier to read the differential data on the global bit line and the neighbor global bit line.
