ECC Memory Not Safe from Rowhammer Attack

Posted on by

Researchers have proven for the first that that error-correcting code (ECC) memory can be affected by the same bit-flipping attack known as Rowhammer that plagues regular DRAM memory. Rowhammer is a memory defect first documented in 2014 that occurs w… Continue reading ECC Memory Not Safe from Rowhammer Attack→
