A memory comprises a two dimensional array of memory cells. Each memory cell comprises a first transistor, a second transistor and a capacitor. A multi-bit datum is stored as one of a plurality of voltage signal levels driven over a vertical input signal line and further across a source and a drain of the first transistor to be stored onto a gate of the second transistor. The first transistor is selected by a horizontal WR control line. The gate of the second transistor is connected to a first terminal of the capacitor. A second terminal of the capacitor is connected to a horizontal RD control line. The RD control line is driven to couple the second transistor to drive a signal onto a vertical output signal line during a read of the stored signal on the gate.
