Abstract
Embodiments include methods, systems and circuits for operating an error trapping logic circuit in a memory device. Aspects include receiving, during a first clock cycle, data and check bits for the data from a memory location and determining, during the first clock cycle, whether the data includes any error by calculating an error syndrome from the data and the check bits. Aspects also include determining, during a second clock cycle, a type of the error based on a full decoding of the error syndrome. Aspects further include determining whether to store the data, the check bits and the error syndrome in trap registers of the error trapping logic circuit based on an operating mode of the error trapping logic circuit and the type of the error.
