Abstract: Systems and methods are disclosed for implementing error correction control regions (ECC) in a memory device without the need to ECC protect the entire memory device. An exemplary method comprises defining one or more ECC regions in a memory device, the memory device coupled to a system on a chip (SoC). An ECC block is provided on the SoC, the ECC block in communication with the one or more ECC regions in the memory device. A determination is made with the ECC block whether to store data in a first of the one or more ECC regions. Responsive to the determination ECC bits are generating for, and interleaved with, the received data and interleaved ECC bits and data are caused to be written to the first ECC region. Otherwise, received data is sent to a non-ECC region of the memory device.
