ABSTRACT
Free-p—fine-grained remapping with error checking and correcting (ECC) and embedded pointers—remaps worn-out nonvolatile RAM (NVRAM) blocks at a fine granularity without requiring large dedicated storage and protects NVRAM against both hard and soft errors. Furthermore, Free-p can be implemented purely in the memory controller, avoiding custom NVRAM devices.
INDEX TERMS
error correction codes, nonvolatile memory, phase-change random access memory, reliability, resistance, memory
