Within the generalized (non-Markovian) multidimensional Langevin approach, the time and energy characteristics of symmetric fission of highly excited heavy nuclei are studied. In two-dimensional space of the collective deformation parameters, it is considered a nuclear descent from the top of the fission barrier to the scission point. The distributions of descent times and total kinetic energy of fission fragments are calculated as functions of memory time, measuring the relative size of memory effects in the collective dynamics. We found that the peculiarities of the non-Markovian dynamics at fairly large values of the memory time are reflected in the saturation of the mean time of motion from the saddle to scission with the growth of the strength of memory effects in the system.
