Abstract
Space efficient data integrity checks are disclosed herein. During a write operation of a first data to a location, a combined integrity value is calculated based on a first data integrity value of the first data and the location. The first data is stored at the location along with the combined integrity value. During a read operation of the first data, the first data is read from the location along with the combined integrity value, and a second data integrity value is calculated for the read first data. Data corruption and/or location errors can be determined based on the second data integrity value, the location, and the combined integrity value.
