It is shown that, when examining the characteristics of the storage of information in dynamic memory chips based on the sale of computer memory widely used software Matlab/Simulink. Batch Simulink is an integral part of the MATLAB simulation systems and comes along with it. The basis of his work is visually-oriented programming principles using models presented in the form of blocks, structured by sections of the library. The problem with the help of specialized units to build a model cell byte Simulink dynamic memory running under conditions of natural background radiation and a comparative analysis of noise in the absence of data storage and Use redundant code Hamming. First model of dynamic memory cells on natural background radiation and the influence of noise on reliability of Hamming code information. The proposed model is used to study the work of controlling the test work RAM, as well as the impact of elevated radiation levels, especially in outer space on dynamic reliability of memory chips.
