Abstract: The probability model of a class of combined pseudo -random sequence variable memory is suggested and analyzed, of which the main characteristic is given. The information leak caused by time-variable function while the output sequence is turning into the input sequence is analyzed. The quasi -like sequence method by which the output sequence constructs the input sequence of variable-memory threshold is suggested in this paper.

Key words: variable-memory, correlation analysis, threshold
