Abstract
A memory includes a memory core, an error correction code (ECC) engine, and an error determination circuit. The ECC engine is configured to generate an error correction code to be stored in the memory core together with write data by using the write data during an encoding operation, and to correct an error of read data read from the memory core using the error correction code read from the memory core during a decoding operation. The error determination circuit is configured to determine that, during the decoding operation, a 1-bit error exists when upper index portions of syndromes generated by the ECC engine have odd weights, and to determine that a correctable 2-bit error exists when the upper index portions of the syndromes are one of predetermined even weight patterns.
