Systems and methods for memory representation and management

A storage system comprising:

• a first storage medium;
• a second storage medium;
• a processor configured to communicate with the first storage medium;
• and
• a processor configured to:
• identify a request to allocate memory in the first storage medium, wherein the first storage medium is associated with a first tier of a memory hierarchy;
• in response to the request, represent the memory via at least a first node of a first data structure, wherein the first data structure is associated with the first tier;
• track activity associated with a memory address represented by the first node;
• modify an order for the first node in the first data structure based on the activity, wherein the first node stores an association to a second node in the first data structure, wherein modifying the order includes modifying the association from the second node to a third node;
• modify an association of the first node from the first data structure to a second data structure, wherein the second data structure is associated with a second tier of the memory hierarchy;
• and
• based on modifying the association of the first node, retrieve data from the memory address of the first storage medium and store the data in the second storage medium.
