Abstract
A hybrid memory provides both protected and unprotected storage arrays within a common device. The memory includes shared resources including address decoding, data input and output paths and power supply. Three memory arrays provide the storage capacity in which a first memory serves as unprotected memory and a second and third provide storage for data and error correction codes, respectively.
