A bit line decoder for sensing states of memory cells of a memory array includes D control devices that selectively communicate with (D−1) bit lines of the memory array. (D−2) of the D control devices are arranged in a first level and two of the D control devices are arranged in a second level of the bit line decoder. The (D−2) control devices are connected to each other in series forming (D−3) junctions. (D−3) of the (D−1) bit lines are directly connected to the (D−3) junctions. Log2(D−2) is an integer greater than 2. A control module generates first control signals that deselect a predetermined number of the D control devices and that select two of the (D−1) bit lines that communicate with one of the memory cells. An isolation circuit to isolate the first level from the second level includes a plurality of isolation devices having first ends that communicate with the (D−2) control devices of the first level and second ends that communicate with the two control devices of the second level.
