ABSTRACT:
A method is disclosed of making information contents of memory-cells of a volatile semiconductor memory irretrievable. In a first step a digital pattern is generated and in a second step the information contents are overwritten with the digital pattern at least two times. The digital pattern is predefined, comprising both zeros and ones and overwrites the information contents alternately with its complementary pattern.
