Abstract Compute-in-memory (CIM) based on various devices such as static random access memory (SRAM) and resistive random access memory (RRAM) and other emerging devices such as indium-gallium-zinc-oxide (IGZO) transistor, magnetoresistive RAM (MRAM), and ferroelectric RAM (FeRAM) has been explored for better performance and energy efficiency on neural networks applications. However, CIM based on a single-type device suffers a variety of non-ideal metrics to reach the simultaneous optimal accuracy, density, and energy efficiency. This work presents equivalent-ideal CIM (Eq-CIM), a monolithic 3D(M3D) IGZO-RRAM-SRAM integrated architecture for robust and efficient compute-in-memory enabling equivalent-ideal device metrics. To overcome the non-ideality (variation, endurance, temperature, etc.) of the single-type devices, system-technology co-optimization (STCO) is performed. This work highlights the non-ideality-aware functionality breakdown for robust high accuracy and simultaneous high density/efficiency, by utilizing 2T0C IGZO for temporal activation storage, RRAM for high-density weight storage, and SRAM for accurate CIM. Device-to-algorithm variation transfer is applied to analyze the system-level accuracy. We benchmark Eq-CIM architecture on CIFAR-10/ImageNet, with 5.06×storage density and 5.05×/2.45×area/energy efficiency compared with single-type-device-based CIM, and high robustness (<0.27%accuracy loss) from-40℃ to 120℃.

In the past several decades, the density and performance of transistors in a single chip have been increasing based on Moore’s Law. However, the slowdown of feature size reduction and memory wall in the von Neumann architecture restrict the improvement of system performance and energy efficiency. Thus the requirements of the emerging big data and artificial intelligence applications cannot be met. To address this issue, novel devices and architectures are being explored. Among them, the InGaZnO(IGZO) fieldeffect transistor(FET) device and the computing-in-memory(CIM) architecture can be possible solutions for high-density, high-performance, and high-efficiency applications. Herein, we review the recent progress in IGZO-based FETs for dynamic random access memory(DRAM) applications. The mechanism of IGZO FETs, compact modeling of IGZO transistors, progress of IGZO manufacturing process, IGZO circuit design,and IGZO-based CIM and 3D integration architectures are presented. Furthermore, the challenges and future trends of IGZO research are discussed.

For the non-stop demands for a better and smarter society, the number of electronic devices keeps increasing exponentially;and the computation power, communication data rate, smart sensing capability and intelligence are always not enough. Hardware supports software, while the integrated circuit(IC) is the core of hardware. In this long review paper, we summarize and discuss recent trending IC design directions and challenges, and try to give the readers big/cool pictures on each selected small/hot topics. We divide the trends into the following six categories, namely, 1) machine learning and artificial intelligence(AI) chips, 2) communication ICs, 3) data converters, 4) power converters, 5) imagers and range sensors, 6) emerging directions. Hope you find this paper useful for your future research and works.

人工智能与物联网时代,大数据模型驱动的应用场景和计算任务层出不穷,极大促进了国家数字化发展.然而,传统冯·诺依曼(John von Neumann)体系架构的硬件系统由于存算分离的结构特点导致存储墙瓶颈,在数据密集型应用中消耗了大量的数据搬运成本,抑制了能效性能提升.存算一体技术是后摩尔(Moore)时代背离传统架构系统的新型计算范式,利用存储单元器件、电路内在特性,将基本的计算逻辑任务融入存储单元之中,从而消除数据搬运开销,有望实现智能计算硬件平台能效性能的显著提升.本文以契合存算一体技术的存储器件电路为切入点,概述基于传统互补金属氧化物半导体(complementary metal oxide semiconductor,CMOS)和新型非易失存储器件代表铁电晶体管的存算一体电路,并从器件、架构芯片、算法应用等层次讨论存算一体电路的跨层次协同设计优化方法.
