Title: STORAGE DEVICE HAVING IMPROVED WRITE UNIFORMITY STABILITY
Abstract:
A machine readable storage medium containing program code that when processed by a processor causes a method to be performed a method is described. The method includes executing a wear leveling routine by servicing cold data from a first queue in a non volatile storage device to write the cold data. The method also includes executing a garbage collection routing by servicing valid data from a second queue in the non volatile storage device to write the valid data. The method also includes servicing host write data from a third queue in the non volatile storage device to write the host write data wherein the first queue remains fixed and is serviced at a constant rate so that a runtime size of the third queue is not substantially affected by the wear leveling routine.
