Samsung 16GB Memory Pc4-21300 DDR4 2666MHz. This memory module is an ECC (Error-Correcting Code) registered DDR4 SDRAM module. The ECC feature is a type of memory error detection and correction technique that ensures data integrity in memory modules. ECC memory detects and corrects single-bit errors in real-time. This is important for mission-critical applications, such as servers, where data integrity is crucial. Single-bit errors occur when a single bit (0 or 1) in memory is flipped due to various factors like electromagnetic interference (EMI), cosmic rays, and so on.
