The electric device ( 1, 100 ) has a body ( 2, 101 ) with a resistor ( 7, 250 ) comprising a phase change material being changeable between a first phase and a second phase. The resistor ( 7, 250 ) has an electric resistance which depends on whether the phase change material is in the first phase or the second phase. The resistor ( 7, 250 ) is able to conduct a current for enabling a transition from the first phase to the second phase. The phase change material is a fast growth material which may be a composition of formula Sb<SUB>1-c</SUB>M<SUB>c </SUB>with c satisfying 0.05<=c<=0.61, and M being one or more elements selected from the group of Ge, In, Ag, Ga, Te, Zn and Sn, or a composition of formula Sb<SUB>a</SUB>Te<SUB>b</SUB>X<SUB>100-(a+b) </SUB>with a, b and 100-(a+b) denoting atomic percentages satisfying 1<=a/b<=8 and 4<=100-(a+b)<=22, and X being one or more elements selected from Ge, In, Ag, Ga and Zn.
