An example embodiment is a circuit for determining a binary value of a memory cell. The circuit includes shunt capacitors having different capacitances to selectively couple with the memory cell, and a controller configured to iteratively charge the shunt capacitors to a first voltage until a selected shunt capacitor causes the first voltage to decay through the memory cell to a first reference voltage within a predetermined time range, determine a binary value of the most significant bits of the memory cell based on the selected shunt capacitor, charge the selected shunt capacitor to a second voltage after determining the binary value of the most significant bits of the memory cell, and determine a binary value of the least significant bits of the memory cell based on a decay of the second voltage at the selected shunt capacitor through the memory cell. |
