Setting Durations for which Data is Stored in a Non-Volatile Memory based on Data Types

Abstract:

An electronic device includes a non-volatile memory and a memory controller. The memory controller selects, from the type-duration table, a duration for which data of a type of data is to be stored in a non-volatile memory. The memory controller writes the data to the non-volatile memory using values of one or more write parameters selected by the memory controller based on the duration. The memory controller sets an expected lifetime value in a record for the data in the expected lifetime table to indicate an expected lifetime of the data in the non-volatile memory.
