Memristive Cluster Based Compact High-Density Nonvolatile Memory Design and Application for Image Storage

Abstract

As a new type of nonvolatile device, the memristor has become one of the most promising technologies for designing a new generation of high-density memory. In this paper, a 4-bit high-density nonvolatile memory based on a memristor is designed and applied to image storage. Firstly, a memristor cluster structure consisting of a transistor and four memristors is designed. Furthermore, the memristor cluster is used as a memory cell in the crossbar array structure to realize the memory design. In addition, when the designed non-volatile memory is applied to gray scale image storage, only two memory cells are needed for the storage of one pixel. Through the Pspice circuit simulation, the results show that compared with the state-of-the-art technology, the memory designed in this paper has better storage density and read–write speed. When it is applied to image storage, it achieves the effect of no distortion and fast storage.

Efficient Data Transfer and Multi-Bit Multiplier Design in Processing in Memory

“…Based on IMPLY, Jiang [ 22 ] and Huang et al [ 49 ] then proposed a multi-input model. As shown in Figure 4 and Figure 5 , a memristor P2 is added to the implication logic.…”

“…Memristors are a preferred choice for studying new types of non-volatile memory due to their non-volatile characteristics [ 20 ]. In 2014, Zangeneh et al proposed a memristor memory with a crossbar array called 1T1M, based on which memristor-based multivalued memories are designed [ 21 , 22 ]. Additionally, Sun et al proposed a 3D memristive multivalue memory [ 23 ].…”

A Robust Memristor-Enhanced Polynomial Hyper-Chaotic Map and Its Multi-Channel Image Encryption Application

“…Compared to the three fundamental circuit components, resistors, capacitors, and inductors, memristors possess unique memory resistance functional characteristics. Due to this distinctive memory property, memristors can find applications in various fields, including intelligent computing [2,3], neural networks [4][5][6], data mining [7], memory devices [8][9][10], and chaotic circuits [11][12][13], among others. However, because memristors have not been physically realized in the real world, research on memristors and memristor circuits has not attracted the attention of researchers.…”
