Abstract: An in-band error correcting code (ECC) module intercepts input/output (I/O) operations directed to a memory. The in-band ECC module determines whether the I/O is directed to data that needs to be protected against error. In response to determining that the I/O is directed to data that needs to be protected against error, the in-band ECC module directs a memory controller to store or access ECC data corresponding to the data in a first preassigned area of the memory, and to store or access the data in a second preassigned area of the memory.
