Abstract

Systems and methods using a three-dimensional memory device with a number of memory cells disposed vertically in a number of pillars arranged along a horizontal direction can be used in a variety of applications. In various embodiments, pillars of memory cells may be disposed between lower and upper digitlines respectively coupled to different sense amplifiers to provide read/write operations and refresh operations. In various embodiments, a three-dimensional memory device having an array of memory cells vertically arranged in pillars may include a sense amplifier and digitline with a static random access memory cache, where the static random access memory cache is disposed below the array of memory cells in the same die. Additional apparatus, systems, and methods are disclosed.
