Abstract
A method in a memory device implementing error correction includes setting an error correction event register to a first value; accessing a memory location in the first memory array in response to a memory address; retrieving stored memory data from the accessed memory location in the first memory array and retrieving error correction check bits corresponding to the accessed memory location from the second memory array; checking the retrieved memory data for bit errors using the retrieved check bits; in response to a bit error being detected in the retrieved memory data, generating corrected memory data using the retrieved check bits and asserting an error correction event signal; and in response to the error correction event signal being asserted, setting the error correction event register to a second value.
