Abstract: Integrated circuits with memory elements may be provided. Integrated circuits may include memory error detection circuitry that is capable of correcting single-bit errors, correcting adjacent double-bit errors, and detecting adjacent triple-bit errors. The memory error detection circuitry may include encoding circuitry that generates parity check bits interleaved among memory data bits. The memory error detection circuitry may include decoding circuitry that is used to generate output data and error signals to indicate whether a correctable soft error or an uncorrectable soft error has been detected. The output data may be written back to the memory elements if a correctable soft error is detected. The memory error detection circuitry may be operable in a pipelined or a non-pipelined mode depending on the desired application.
