A system based on computational memory and memory systems, such as embodied in computational solid state drive (SSD) technology, as described herein, reduces processor utilization and/or bus bandwidth utilization. The system is enabled to perform computational techniques (e.g., searching, computing, and/or accessing) using resources of the computational SSDs, rather than processor and/or bus resources, thus reducing or minimizing information movement between processing elements and storage devices. Computational SSD technology enables managing, organizing, selecting, and analyzing ever increasing data volume in real time. A computational SSD is enabled to store and to operate on data locally, e.g., using resources of the computational SSD. Thus, processing, storage, and bandwidth requirements of a system are reduced by using the computational SSD.

Abrégé
A semiconductor device includes a staircase structure and an extension part. The stacked structure is located on a dielectric substrate. The staircase structure includes a plurality of conductive layers and a plurality of insulating layers stacked alternately on each other. The extension part is located at an end of the lower stair part of the staircase structure. The resistance value of the extension part is different from the resistance value of the plurality of conductive layers.
