Abstract (en)

[origin: DE10255102B3] The device is connected to at least one data line and has at least one memory node (K1,K2), at least one selection transistor (M5) connected to the first node, a first data line (BL), a first word line (WL1) and an arrangement (M7) for adapting the leakage current that causes a total leakage current from at least one bit line (BL) into the cell independent of the memory state of the cell, especially in the non-selected state.
