ABSTRACT:
A data storage device such as a DRAM memory having a plurality of data storage cells10is disclosed. Each data storage cell10has a physical parameter which varies with time and represents one of two binary logic states. A selection circuit16, writing circuits18and a refreshing circuit22apply input signals to the data storage cells to reverse the variation of the physical parameter with time of at least those cells representing one of the binary logic states by causing a different variation in the physical parameter of cells in one of said states than in the other.
