Abstract
A storage system and method for automatic data phasing are disclosed. In one embodiment, a storage system is configured to receive, from a host, data to be written in the memory and an indication of an expected lifespan of the data; and determine whether to perform a garbage collection operation on the data based on the expected lifespan of the data. Other embodiments are provided.
Claims20
A storage system comprising:
- a memory;
- and
- a controller configured to:
- receive, from a host, data to be written in the memory and an indication of an expected lifespan of the data;
- and
- determine whether to perform a garbage collection operation on the data based on the expected lifespan of the data.
3 more elements
A method comprising:
- performing the following in a storage system comprising a memory:
- receiving, from a host, data to be written in the memory, the data having an indicated lifetime;
- after the lifetime of the data has expired, invalidating the data in a logical-to-physical address table even though the data is otherwise valid;
- and
- performing garbage collection on valid data in the logical-to-physical address table, wherein invalidating the data in the logical-to-physical address table even though the data is otherwise valid causes the data to avoid garbage collection.
2 more elements
A storage system comprising:
- a memory;
- means for receiving data to be written in the memory and an indication of a lifetime of the data;
- and
- means for foregoing garbage collection on the data in response to the lifetime of the data expiring.
