Explanation

ECC (Error-Correcting Code) RAM can detect and automatically correct single-bit memory errors in real time, allowing the system to continue operating normally even when data corruption occurs. It uses additional bits to store parity/checksum information alongside data. This makes ECC RAM essential in servers and workstations where data integrity is critical. Non-parity RAM (A) has no error detection or correction capability at all. Dual-channel (B) is a memory architecture configuration that improves bandwidth by using two RAM modules simultaneously - it has no error correction capability. Buffered (registered) RAM (C) uses a register between the memory controller and RAM modules to improve stability in high-capacity configurations but does not provide error correction on its own.
