Which type of RAM detects and corrects errors on the fly?

ECC RAM, or Error-Correcting Code RAM, is designed specifically to detect and correct data corruption in real-time. This type of memory uses additional bits to store error correction codes, which allows it to identify when an error occurs and fix it on the fly without any downtime. This is particularly important in mission-critical systems where data integrity is crucial, such as servers and medical devices.

In contrast, other types of RAM, such as SDRAM, DRAM, and SRAM, do not have built-in capabilities for error detection and correction. SDRAM (Synchronous Dynamic RAM) is known for its speed, DRAM (Dynamic RAM) is a more standard type of volatile memory used in most applications, and SRAM (Static RAM) is faster and used for cache memory, but none of these types provide the error-correcting functions that ECC RAM does. Therefore, ECC RAM stands out as the correct choice for systems requiring high reliability and data integrity.
