Cross-point architecture, while being appealing in consideration of high integration density, suffers from leakage through sneak paths across the array. The current flowing half-accessed and some cases, unaccessed cells (and corresponding power) are important determinants array performance. Proper estimation these components is computationally challenging often demands rigorous simulation efforts. This paper presents a efficient compact model to assess cross-point employing threshold switch selectors. We provide closed form mathematical expressions that govern our explain derivation methodologies. analyze verify validity by cross-checking with results conventional simulations. shows excellent matching (~99% accuracy) simulations for different sizes (16×16 256×256). has been tested various ranges selector OFF resistance (0.1 MΩ 1 GΩ), interconnect (1 mΩ/□ 10 Ω/□) access voltage (0.2V 1V). test show accurate response comparison those obtained intensive
