Abstract:
Embodiments of the invention relate generally to semiconductors and memory technology, and more particularly, to systems, integrated circuits, and methods to preserve states of memory elements in association with data operations using variable access signal magnitudes for other memory elements, such as implemented in third dimensional memory technology. In some embodiments, a memory device can include a cross-point array with resistive memory elements. An access signal generator can modify a magnitude of a signal to generate a modified magnitude for the signal to access a resistive memory element associated with a word line and a subset of bit lines. A tracking signal generator is configured to track the modified magnitude of the signal and to apply a tracking signal to other resistive memory elements associated with other subsets of bit lines, the tracking signal having a magnitude at a differential amount from the modified magnitude of the signal.
