Which of the following memory features will allow a server to correct up to 4-bit memory errors?

ECC (Error-Correcting Code) memory typically detects and corrects single-bit errors and can detect (but not correct) two-bit errors, but it is not designed to correct up to 4-bit errors.

Registered (or Buffered) memory improves stability by reducing electrical load on the memory controller, but it does not provide error detection or correction capabilities itself.

Chipkill is a memory technology, developed by IBM, that uses a more robust error correction code to protect against multiple-bit errors within a memory chip, including simultaneous 4-bit errors, providing a higher level of data integrity than standard ECC.

Parity memory is an older error detection method that can detect single-bit errors but cannot correct them.
