EOS memory (for ECC on SIMMs) is an error-correcting memory system ''built into''
SIMM
A SIMM (single in-line memory module) is a type of memory module containing random-access memory used in computers from the early 1980s to the early 2000s. It differs from a dual in-line memory module (DIMM), the most predominant form of memory ...
s, used to upgrade
server-class computers without built-in ECC memory support. The EOS SIMM itself does the error checking, with reduced need for
ECC memory
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 c ...

The technology was introduced by
IBM in the mid-1990s.
