    This is the most comprehensive CA lecture i have seen so far.

    These lectures are a great refresher. Although I did want to ask the Dr if a memory system with ECC would eliminate the row hammer exploit.

      Not a system with conventional ECC. Many works show that relatively simple ECC employed in modern memory chips and memory controllers is not enough to detect or correct the RowHammer induced bitflips. See, for example:
      "Uncovering In-DRAM RowHammer Protection Mechanisms: A New Methodology, Custom RowHammer Patterns, and Implications", appears at MICRO 2021.
