NONVOLATILE, CAPACITIVELY READABLE MEMORY ELEMENTS

A method for reading out a non-volatile memory element having at least two stable states 0 and 1. This memory element comprises at least one resistive memory cell, which encodes the two states 0 and 1 into a state HRS having higher electrical resistance and a state LRS having lower electrical resistance. In the two states 0 and 1, the memory element has differing capacitances C0,1; this difference is used to determine which state is present. A memory element is selected in which a fixed capacitance that is independent of the state of the memory cell is connected in series with the memory cell. A series connection of a resistive memory cell with a fixed capacitance, instead of with a second resistive memory cell, improves the signal strength during capacitive read-out. The second memory cell becomes indispensable for the memory function when the memory element is read out capacitively. Moreover memory elements were developed which combine a field effect transistor or a DRAM structure with a resistive memory cell or an antiserial series connection of such memory cells.
