RowPress: Amplifying Read Disturbance in Modern DRAM Chips. (arXiv:2306.17061v1 [cs.CR])

Memory isolation is critical for system reliability, security, and safety.
Unfortunately, read disturbance can break memory isolation in modern DRAM
chips. For example, RowHammer is a well-studied read-disturb phenomenon where
repeatedly opening and closing (i.e., hammering) a DRAM row many times causes
bitflips in physically nearby rows.

This paper experimentally demonstrates and analyzes another widespread
read-disturb phenomenon, RowPress, in real DDR4 DRAM chips. RowPress breaks
memory isolation by keeping a DRAM row open for a long period of time, which …
