ABSTRACT:
A data storage device includes a plurality of data storage units, a physical random number generator with a noise source based on a physical noise process, for generating a random number, and a replacer for selecting a data storage unit wherein data is to be stored, depending on the random number. Selecting, on the basis of genuine random numbers, data storage units and/or lines to be replaced in the cache.
