1. A charge trapping non-volatile organic memory device, comprising:
an organic-inorganic composite film, in which a metal oxide is dispersed in a polymer matrix, as a trapping layer for trapping charges,
wherein the charge trapping non-volatile organic memory device has retention satisfying the following Equation 1
70%≤MW(t)/MW(0)*100
wherein, in Equation 1, MW(0) is an initial memory window (V) of the charge trapping nonvolatile organic memory device under 300K, and MW(t) is a memory window at 104 sec.
