Abstract
In a closed-loop garbage collection system a comparator receives a first target time indicating when a first superblock of memory is expected to be filled based on a first write rate for a first write cursor writing data units into the first superblock. The comparator further receives a negative loop feedback based on one or more elements from the garbage collection process. The comparator determines a first garbage collection rate based on the first target time and the negative loop feedback, where the first garbage collection rate is calculated to provide a free empty superblock to the first write cursor within a range of time of the first target time. The comparator sends instructions to a garbage collection manager to perform a garbage collection process at the first garbage collection rate, wherein an outcome of the garbage collection process is incorporated into the negative loop feedback sent to the comparator.
