Abstract

Methods, systems, and devices for storing parity during refresh operations are described. In some examples, refresh operations may be performed on a memory device when the memory device is idle. For example, a refresh operation may entail performing a logical operation on first data and a first set of parity bits and second data and a second set of parity bits. The logical operation may generate a third set of parity bits which may be used for data retention purposes. Moreover, during a read operation, the third set of parity bits may be used to recover corrupt or otherwise invalid data in the event of an error.
