Abstract
A memory system or flash card may include memory maintenance scheduling that improves the endurance of memory. Certain parameters, such as temperature, are measured and used for scheduling maintenance. For example, memory maintenance may be performed or postponed depending on the ambient temperature of the card. The memory maintenance operations may be ranked or classified (e.g. in a memory maintenance queue based on priority) to correspond with threshold values of the parameters for a more efficient scheduling of memory maintenance. For example, at a low temperature threshold, only high priority maintenance operations are performed, while at a higher temperature threshold, any priority maintenance operation is performed.
