Abstract

HBM (high bandwidth memory) is an emerging technology for high performance computing, but it has a different structure from traditional memory, and thus a new solution is needed. In this brief, we present an ECC (error correcting code) configuration method for SWD (sub-wordline driver) fault correction in the two-tiered ECC structure of HBM. Existing method does not have the correction capability to cover the entire range of a SWD cluster fault. In this brief, the SWD fault correction capability of the proposed method is presented through mathematical inference. And the simulation results also showed the same correction capability as the inference. And it shows the result of reducing the overhead and latency of encoder and decoder hardware when compared to the existing method.

HBM体系结构中两层ECC纠错新方法

HBM （high bandwidth memory，高带宽内存）是一种新兴的高性能计算技术，但其结构与传统内存不同，因此需要一种新的解决方案。在本文中，我们提出了一种用于HBM两层ECC结构中SWD（子字行驱动程序）故障校正的ECC（纠错码）配置方法。现有的方法不具备覆盖整个SWD集群故障范围的校正能力。通过数学推理，给出了该方法的SWD故障校正能力。仿真结果也显示了与推理结果相同的校正能力。结果表明，与现有方法相比，该方法降低了编码器和解码器硬件的开销和延迟。
