A controller for a plasma display having a first drive unit to apply voltage to a sustain electrode of a display unit having a memory function and a second drive unit to apply voltage to an address electrode of the display unit. The first drive unit has a discharge control unit to control the discharge wave form of the voltage applied to the sustain electrode of the display unit. The discharge control unit has a delay element and a switching element connected in series between sustain electrodes. Alternatively, the control unit has a delay element and a switching element connected in series between the sustain electrodes and a constant voltage discrimination element connected in parallel with the delay element.
