Memory system, control system and method of predicting lifetime
A memory system according to an embodiment may have an integration unit and a prediction unit. The integration unit may detect substrate current flowing through a substrate of a non-volatile memory when the non-volatile memory with a memory cell which has binary or multivalued being the binary or more is written/erased. The integration unit may records an integration value of the detected substrate current into a storage. The prediction unit may predict a lifetime of the non-volatile memory based on the integration value which is recorded on the storage.
