At temperatures lower than 200 K the photomemory effect has been observed in ZnTe-Cd_{1-x}Mn_{x}Te_{1-y}Se_{y} heterojunctions. The persistent photoconductivity can be achieved either by illumination from an external light source or by a self-absorption of the electroluminescence radiation when a voltage of about 10 V for a few seconds is applied to the diode. Current-voltage characteristics are of the form I~ V^{m}. The capacitance and electroluminescence measurements show that the photomemory effect in ZnTe-Cd_{1-x}Mn_{x} Te_{1-y}Se_{y} heterojunctions can be caused by the bistable nature of the In dopant in the Cd_{1-x}Mn_{x}Te_{1-y}Se_{y} substrate. In the high resistivity interface layer and the substrate material indium forms centers similar to DX-like centers in Zn_{x}Cd_{1-x}Te and Cd_{1-x}Mn_{x}Te.
