Memory with built-in features to recover from errors is also known as:

The correct answer is D. ECC. ECC (Error-Correcting Code) memory can detect and automatically correct single-bit memory errors and detect (though not correct) multi-bit errors. This makes it essential for servers and mission-critical systems where data integrity must be guaranteed. Parity (A) can only…

Explanation

ECC (Error-Correcting Code) memory can detect and automatically correct single-bit memory errors and detect (though not correct) multi-bit errors. This makes it essential for servers and mission-critical systems where data integrity must be guaranteed. Parity (A) can only detect errors, not correct them. SDRAM (B) describes a synchronous DRAM technology, not an error-correction feature. DDR (C) refers to Double Data Rate transfer speed, also unrelated to error correction.
