摘要

本文提出了模拟软信息译码电路用于多级存储器的错误保护,提供了比二进制纠错码更强的错误保护。然后可以在不增加软错误率的情况下减小电池电容。模拟解码器以非常低的面积要求执行软信息解码。介绍了一种多级模拟接口电路,用于MLDRAM信号的模拟解码。我们还运用基本信息理论揭示了编码在多层次记忆中的可能性和局限性。

Analog soft decoding for multi-level memories
This paper proposes analog soft-information decoding circuits for error protection in multi-level memories, providing stronger error protection than binary error-correcting codes. The cell capacitance can then be reduced without an increase in the soft error rate. Analog decoders perform soft-information decoding with very low area requirements. We introduce a multi-level analog interface circuit for analog decoding of MLDRAM signals. We also apply basic information theory to reveal the possibilities and limitations of coding in multi-level memories.
