Radix Coverage for Hardware Common Weakness Enumeration (CWE) Guide (updated)
By Cycuity (Formerly Tortuga Logic) - 31 Jan, 2024 - Comments: 0

MITRE’s hardware Common Weakness Enumeration (CWE) database aggregates hardware weaknesses that are the root causes of vulnerabilities in deployed parts. In this 100+ page guide, each CWE is listed along with a Radix template Security Rule that can be filled in with design-specific signals and used as a baseline test for the respective CWE. To learn more about a specific CWE, follow the li... » read more

How To Stop Row Hammer Attacks
By Ed Sperling - 30 Jan, 2024 - Comments: 0

Row hammer is a well-publicized target for cyberattacks on DRAM, and there have been attempts to stop these attacks in DDR4 and DDR5, but with mixed results. The problem is that as density increases, distance decreases, making it more likely that flipped bit cell in one row can disturb a bit cell in another, and that bits flipped across an entire row can flip another row. Steven Woo, fellow and... » read more
