    摘要: A method of driving a nonvolatile memory device including applying a reset voltage to a unit memory cell, reading a reset current of the unit memory cell, confirming whether the reset current is within a first current range, if the reset current is not within the first current range, changing the reset voltage and applying a changed reset voltage or applying again the reset voltage to the unit memory cell after applying a set voltage to the unit memory cell, if the reset current is within the first current range, confirming whether a difference between the present reset current and an immediately previous set current is within a second current range, and, if the difference is not within the second current range, applying the reset voltage or applying again the reset voltage to the unit memory cell after applying a set voltage to the unit memory cell.

    摘要: Example embodiments relate to a resistive random access memory (RRAM) and a method of manufacturing the RRAM. A RRAM according to example embodiments may include a lower electrode, which may be formed on a lower structure (e.g., substrate). A resistive layer may be formed on the lower electrode, wherein the resistive layer may include a transition metal dopant. An upper electrode may be formed on the resistive layer. Accordingly, the transition metal dopant may form a filament in the resistive layer that operates as a current path.

    摘要: A memory device includes a memory cell. The memory cell includes: a bipolar memory element and a bidirectional switching element. The bidirectional switching element is connected to ends of the bipolar memory element, and has a bidirectional switching characteristic. The bidirectional switching element includes: a first switching element and a second switching element. The first switching element is connected to a first end of the bipolar memory element and has a first switching direction. The second switching element is connected to a second end of the bipolar memory element and has a second switching direction. The second switching direction is opposite to the first switching direction.
