A device for storing data includes a sequence generator configured to generate a first number sequence that is a pseudorandom number sequence, a cross-correlation unit configured to produce a second number sequence that is a cross-correlation between the first number sequence and a third number sequence, and a write and read unit configured to write the second number sequence in memory and read the second number sequence from the memory, wherein the cross-correlation unit is further configured to reconstruct the third number sequence by obtaining a cross-correlation between the first number sequence and the second number sequence read from the memory.
