Abstract
Systems and methods are disclosed for identifying and compressing rarely used data. A storage module may include a memory and a storage controller in operative communication with the memory. The storage controller is configured to identify an access of data stored at a first portion of the memory; determine, based on a first value of the access counter associated with the identified access and a second value of the access counter, that an age of the data stored at the first portion of the memory exceeds a threshold; identify data stored at a second portion of the memory that is associated with a third value of the access counter, where the third value of the access counter is within a range of the first value of the access counter; and compress together at least the data stored at the first and second portions of the memory.
