Abstract: Systems and methods of testing a reference cell in a memory array are disclosed. In a particular embodiment, a method includes coupling a first reference cell of a first reference cell pair of a memory array to a first input of a first sense amplifier of the memory array. The method also includes providing a reference signal to a second input of the first sense amplifier. The reference signal is associated with a second reference cell pair of the memory array.
