Wear-focusing of non-volatile memories for improved endurance

A system comprising:

• a memory logically divided into a plurality of regions, the plurality of regions including a first region and a second region, the first region and the second region implemented by the same memory technology, and the memory subject to degradation as a result of write operations;
• and
• a memory controller in communication with the memory, the memory controller configured to perform a method, the method comprising:
• receiving write data;
• classifying the write data as dynamic data or static data, the classifying including comparing a timestamp associated with a write address for the write data with a programmable threshold value;
• in response to classifying the write data as dynamic data performing:
• encoding the write data using a first type of encoding;
• and
• storing the write data encoded using the first type of encoding in the first region of the memory;
• and
• in response to classifying the write data as static data performing:
• encoding the write data using a second type of encoding;
• and
• storing the write data encoded using the second type of encoding in the second region of the memory.

A computer program product for storing data in memory, the computer program product comprising:

• a non-transitory tangible storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising:
• receiving write data to be written into a memory that is logically divided into a plurality of regions, the plurality of regions including a first region and a second region, the first region and the second region implemented by the same memory technology, and the memory subject to degradation as a result of write operations;
• classifying the write data as dynamic data or static data, the classifying including comparing a timestamp associated with a write address for the write data with a programmable threshold value;
• in response to classifying the write data as dynamic data performing:
• encoding the write data using a first type of encoding;
• and
• storing the write data encoded using the first type of encoding in the first region of the memory;
• and
• in response to classifying the write data as static data performing:
• encoding the write data using a second type of encoding;
• and
• storing the write data encoded using the second type of encoding in the second region of the memory.
