Would you like to know the difference between “Static Faults” and “Dynamic Faults”? Watch the iSTART Class now to explore how algorithms identify errors.

“Static Faults” and “Dynamic Faults” are two types of errors in memory. In simple terms, the difference between them is how and when the errors occur. A “Static Fault” is an error that can be detected in a single operation. It’s like an obvious problem that appears immediately when we perform an action, such as pressing a button that doesn’t respond. For example, if a memory cell always outputs “0” and cannot be changed, that’s a static fault.

On the other hand, a “Dynamic Fault” requires multiple operations to trigger. It’s like a more complicated issue that needs specific conditions or actions to manifest. For example, a memory cell might only produce an error after undergoing a specific series of read and write operations.

In summary, the key difference between static and dynamic faults is how they appear. Static faults are evident and can be discovered in a single operation, while dynamic faults need specific conditions and multiple operations to be revealed. Additionally, the static faults can occur in various technology nodes, while dynamic faults typically emerge in high-end processes. Many applications today are gradually transitioning towards advanced technology nodes, which is also a trend to watch out for.
