A novel method for scanning bit parity in a memory array, and a circuit for implementing it, are disclosed. In a memory array that has one or more rows of memory cells, the method for checking data parity includes storing a plurality of data bits in the memory cells, scanning a row of memory cells independently of a memory read operation to ascertain the stored data bits; and determining parity for the row of memory cells by the results of the scanning. The method is accomplished by means of a dedicated parity scanning circuit.
