Abstract

See full text

Systems and methods are disclosed for cache data value tracking. In an embodiment, a controller may be configured to select data; set a node weight for the data representing a cache hit potential for the data; store a first time stamp value for the data representing when the data was accessed; and store the data in a cache memory based on the node weight and the first time stamp value. In another embodiment, a method may comprise setting a node weight for data associated with a data access command, storing a first access counter value for the data representing a number of times new data has been stored to the cache memory when the data was accessed, and removing the data from the cache memory or maintaining the data in the cache memory based on the node weight and the first access counter value.
