Van der Waals Ferroelectric Semiconductor Field Effect Transistor for In-Memory Computing

Abstract: In-memory computing is a highly efficient approach for breaking the bottleneck of von Neumann architectures, i.e., reducing redundant latency and energy consumption during the data transfer between the physically separated memory and processing units. Herein we have designed a in-memory computing device, a van der Waals ferroelectric semiconductor (InSe) based metal-oxide-ferroelectric semiconductor field-effect transistor (MOfeS-FET). This MOfeS-FET integrates memory and logic functions in the same material, … Show more

“…In addition to the memory application, the vdW ferroelectric semiconductor field-effect transistor shows great potential for in-memory computing. For example, Liao et al [77] constructed an InSe-based metal-oxide-ferroelectric semiconductor field-effect transistor that integrates memory and logic functions in the same ferroelectric material. The OOP ferroelectric polarization in InSe enables data storage and the semiconducting property was adopted for the logic computation; inverter, programmable NAND and NOR Boolean logic operations with non-volatile storage of the results have all been demonstrated nicely.…”

“…This process induces an obvious change in the energy band structure. For instance, MoS 2 has four different crystal structures, whereas MXenes have three predicted structures through theoretical calculations [53][54][55][86][87][88][89]. Ferroelectric insulators are typically used as the gate dielectric in FeFETs, where the conductance of the device channel can be used to determine the polarization direction of the ferroelectric gate material.…”

“…In addition, in the latest study conducted by Xie et al, an FeS-FET was fabricated with an InSe ferroelectric channel that can also be used as NVM [55]. The researchers proved that InSe crystals undergo a change when polarized through high-angle annular dark-field scanning transmission electron microscopy.…”

“…As very large amounts of data processing become more frequent with data transfer between the memory and processor, bottlenecks occur in the traditional von Neumann computing architecture, where the memory and processor are separated. In order to solve such bottlenecks, in-memory computing structures that perform operations during memory access have been proposed as alternatives. In-memory computing not only consolidates memory and processors to reduce the power used for data transfer but also enables parallel computing, enabling high throughput. However, due to a large amount of data and computation, there are still limitations that require huge power consumption and a very large chip size as well as being unusable for mobile and edge computing.…”
