Definition
Memory that stores or generates redundant check information and uses an error-correcting code to detect and correct specified classes of data errors, commonly including automatic correction of single-bit errors.
Application
Used in DRAM and other memory systems to improve data integrity and reliability by correcting recoverable bit errors before data is delivered to the host, reducing the impact of soft errors and scaling-related cell variability.
