摘要:
Storing data in memory using wear-focusing techniques for improved endurance. A method for storing the data includes receiving write data to be written into a memory that is logically divided into a plurality of regions. The plurality of regions includes a first region and a second region that are implemented by the same memory technology. The memory is subject to degradation as a result of write operations. The write data is classified as dynamic data or static data. The write data is encoded using a first type of encoding in response to the write data being classified as dynamic. The write data encoded using the first type of encoding is stored in the first region of the memory. The write data is encoded using a second type of encoding and stored in the second region of the memory in response to classifying the write data as static data.
