Abstract
A method and system for performing garbage collection in a memory is disclosed. Aspects of the exemplary embodiment include dividing garbage collection into atomic operations, including read, write, and block erase; storing read cycle times, write cycle times, and block erase cycle times of the memory; receiving a communication from a processor indicating at least one idle period when an application executing on the processor will not make a request of the memory, wherein the communication indicates a time duration of the at least one idle period; and in response, performing at least one of the garbage collection atomic operations within the time duration, whereby garbage collection can be performed during the at least one idle period, rather than when the memory is substantially full.
