In this paper the problem is considered of essential increasing of fiber memory device informative capacity using optical solitons. It is shown that for optical signals regeneration both Raman scattering and nonstationary parametric amplification of soliton pulses can be applied. On the basis of Raman regeneration the two schemes of fiber memory devices are proposed. The operating of dynamic memory device using soliton information's carriers are estimated. The real-time transformation dynamics of ultrashort pulses is investigated for nonstationary parametric amplification The quantitative assessments of parametric. regeneration process are presented. The advantages of the soliton pulses parametric regeneration in comparison with Raman scattering regeneration are also discussed.
