A storage array, a memory, a reading method thereof, and an electronic device are disclosed. The storage array includes multiple storage cell subarrays, a reference cell column, and a set of reference voltage generation circuits, reference cell switching circuits, and read word line control circuits. The storage cell subarrays and reference cell column in two storage arrays are electrically connected via read bit lines and symmetrically distributed around a read decision unit. The transistors of the reference cells and storage cells are isomorphic and have the same circuit structure. The memory includes at least one pair of open storage arrays, each pair comprising a first storage array, a second storage array, and a set of read decision units. Each storage array is electrically connected to one of the two input terminals of the read decision unit.
