Abstract: One parameter self-memory retrospective time integration scheme of convection-diffusion equation is derived. On the basis of the self-memory dynamics, the stability is discussed by using difference theory. The numerical examples show that this scheme has high accuracy and good stability.

Key words: convection-diffusion equation, self-memory, difference scheme, stability
