Apparatus, systems, and methods for error correction in memory are described. In one embodiment, a memory controller comprises logic to load an error correction codeword retrieved from a memory and apply a first error correction decoder to decode the error correction codeword, wherein the first error correction decoder implements a bit-flipping error correction algorithm which utilizes a variable bit-flipping threshold to determine whether to flip a bit in an error correction codeword. Other embodiments are also disclosed and claimed.
