What is ECC RAM?

 It’s only getting bigger and bigger when it comes to big data. Data accuracy and integrity have become increasingly important for organizations as volumes of information increase.

ECC verifies data transmissions by locating and correcting transmission errors. Generally, it is used in RAM chips with forward error correction (FEC), which ensures the RAM receives and transmits data correctly.

Our goal in this article is to provide you with a general overview of ECC RAM,

What is ECC RAM?

Error-correcting code RAM, or ECC RAM, is a specialized type of memory that detects and fixes the most common errors that could otherwise result in data corruption or system crashes. These are known as single-bit errors and require some explanation.

There are eight memory chips in a bank of RAM. There is a 9th chip in the ECC type. A random bit of memory flips whenever a hard or soft error occurs. The extra chip is purely to detect those flips.

In what ways do single-bit errors occur?

In computing, a bit represents a binary digit (1 or 0), with eight bits forming a byte, the smallest addressable memory unit that computers can read as a single digit or letter. With ECC, the memory system can withstand even single-bit errors: the data read from each word always matches what was written, even if one of the stored bits has been switched.

In most cases, single-bit errors come from hard or soft causes. Temperature and power variations, as well as stress on the hardware, cause problematic single-bit errors. Several factors cause soft single-bit errors, such as magnetic interference and cosmic rays.

How ECC RAM works?

RAM with ECC features an additional memory chip with complex algorithms that identify and rectify errors. Parity checking is how ECC RAM constantly scans data as the system processes it.

Every byte in an ECC RAM has an additional bit known as a parity bit. Parity bits total the 1s in a byte as either even (0) or odd (1) binary digits. The ECC RAM recognizes an error if the parity bit is different from what was previously recorded. A sophisticated code can then recover the original uncorrupted data to correct the mistake.

Why is it necessary? 

Error-correcting memory – as its name implies, it first detects errors and then fixes them. Whenever data integrity is compromised, there are many unintended consequences. Data becomes more vulnerable, posing a security risk; this can result in lost revenue due to failed transactions. You can lose a lot of data if it happens. The worst-case scenario is a complete network failure.

So is ECC RAM worth it?

Yes, it is valid for servers that are used for business-critical functions. Even though crashes are frustrating, they are unlikely to have serious long-term consequences. A single error can have disastrous effects on a server that deals with sensitive information such as customer credit card data.

When processing large volumes of customer data online, ECC RAM is strongly recommended to prevent financial losses caused by corrupted data or reputational damage caused by system failures in the aftermath.

That’s it!
