What does ADDDC stand for?

Adaptive Double DRAM Device Correction

Adaptive Double DRAM Device Correction (ADDDC) is a memory error correction technology used in computer systems to improve the reliability and stability of DRAM (Dynamic Random Access Memory). DRAM is the primary type of memory used in most computers, and it is susceptible to a wide range of errors, including data corruption, bit flips, and other types of memory failures.

ADDDC is designed to detect and correct errors that occur in DRAM by using a combination of hardware and software techniques. The technology is called "Adaptive" because it continuously monitors the error rate in DRAM and adjusts its correction techniques accordingly.
