Abstract: A memory device to use added known data as part of data written to memory cells with redundant data generated according to an Error Correction Code (ECC). The code rate of the ECC may limit its capability to recover from excessive errors in the stored data. To reduce the errors, the added data retrieved from the memory cells can be corrected without using the ECC. Subsequently, remaining errors can be corrected via the ECC. Optionally, the added data can be configured to be the same as the data represented by an erased state of a subset of the memory cells such that when the subset is used to store the added data, the subset remains in the erased state to reduce wearing. Different subsets can be used to store added data for different write operations to distribute the benefit of reduced wearing.
