Abstract

See full text

Embodiments of the invention relate generally to semiconductors and memory technology, and more particularly, to systems, integrated circuits, and methods to implement circuits configured to compensate for parameter variations in layers of memory by adjusting access signals during memory operations. In some embodiments, memory cells are based on third dimensional memory technology. In at least some embodiments, an integrated circuit includes multiple layers of memory, a layer including sub-layers of semiconductor material. The integrated circuit also includes an access signal generator configured to generate an access signal to facilitate an access operation, and a characteristic adjuster configured to adjust the access signal for each layer in the multiple layers of memory.
