Abstract
Memory structures with a plurality of memory cells that each include memory devices in combination with switch devices are provided. The memory device and switch device of each cell are connected in series, and include at least first and second electrodes. The first electrode features a relatively high resistance, to provide a reduced snap current during operation of the memory device. The first electrode with a relatively high resistance can contain or be entirely composed of TiAlN.
