Failure Analysis

Systematic Memory Failure Analysis Flow

Step-by-step methodology for isolating and characterizing memory subsystem failures from system level to silicon.

Memory failures can manifest at multiple levels of the system hierarchy. Our systematic approach helps engineers quickly isolate root causes.

## Step 1: System-Level Observation
Document the failure mode — boot failure, bit errors, thermal throttling, or complete system crash.

## Step 2: Channel-Level Isolation
Use our memory test cards to isolate the failure to a specific channel, rank, or bank group.

## Step 3: Signal-Level Analysis
Capture eye diagrams and perform timing analysis to identify marginal signals.

## Step 4: Physical Debug
For persistent failures, use probing techniques to examine the physical signal integrity at the ball or via level.
