摘要:
新兴的非易失性存储器(NVMs)代表了一种颠覆性技术,它允许从传统的冯·诺依曼架构向更高效的存内计算(CIM)架构进行范式转变。目前已提出几种测试平台来连接NVMs,从而实现对单个单元和交叉阵列结构的表征。然而,这些平台灵活性低,且无法在NVMs上执行CIM操作。因此,我们最近设计并构建了NeuroBreakoutBoard,这是一个高度通用且能够在NVMs上执行CIM的测试平台。我们展示了初步结果,证明在1 kΩ至1 MΩ范围内的相对误差 < 5%,并展示了基于HfO2/Ti的忆阻器单元的开关行为。
英文摘要:
Emerging non-volatile memories (NVMs) represent a disruptive technology that allows a paradigm shift from the conventional von Neumann architecture towards more efficient computing-in-memory (CIM) architectures. Several instrumentation platforms have been proposed to interface NVMs allowing the characterization of single cells and crossbar structures. However, these platforms suffer from low flexibility and are not capable of performing CIM operations on NVMs. Therefore, we recently designed and built the NeuroBreakoutBoard, a highly versatile instrumentation platform capable of executing CIM on NVMs. We present our preliminary results demonstrating a relative error < 5% in the range of 1 k$Ω$ to 1 M$Ω$ and showcase the switching behavior of a HfO$_2$/Ti-based memristive cell.
