Error correction code memory (ECC memory) is a type of computer data storage that uses an error correction code (ECC) to detect and correct n-bit data corruption which occurs in memory. ECC memory is used in most computers where data corruption cannot be tolerated, like industrial control applications, critical databases, and infrastructural memory caches. WebError Correction Codes (ECC) are used in NAND Flash memories to detect and correct bit-errors. With shrinking technology nodes and increased memory complexity, bit error rates continue to grow.
