Process and Apparatus to Reduce Declared Capacity of a Storage Device by Trimming |
摘要 |
Systems, methods, and/or devices are used to reduce declared capacity of non-volatile memory of a storage device in a storage system. In one aspect, the method includes, detecting an amelioration trigger for reducing declared capacity of non-volatile memory of the storage device of the storage system, and in accordance with the detected amelioration trigger, performing an amelioration process to reduce declared capacity of the non-volatile memory of the storage device, the performing including: trimming, in accordance with a trim command received from a host, at least a portion of a set of logical addresses in a logical address space; and reducing declared capacity of the non-volatile memory of the storage device. In some embodiments, the storage device includes one or more flash memory devices. In some embodiments, the method is performed by the storage device. |
