An apparatus comprising a memory and a controller. The memory is configured to process a plurality of read/write operations. The memory comprises a plurality of memory modules. Each memory module has a size less than a total size of the memory. The controller is configured to write user data using a plurality of threshold voltages. The data considered hot-read data is written using a first voltage threshold. The data not considered hot-read data is written using a second voltage threshold. The first voltage threshold reduces an impact on endurance of the memory.
