US 2017/0285956 A1 · Storage Space Management Method and Apparatus

Abstract

A storage space management method and apparatus, where the method and apparatus are applied to a non-volatile memory (NVM). In a feature set that includes M image features of M idle blocks in storage space of the NVM, an idle block whose image feature is highly similar to an image feature of data to be written into the NVM is determined such that the data is written into the idle block. In this way, wear and energy consumption problems are considered during storage space allocation, and a write operation of an idle block in storage space of an NVM can consume less energy, thereby extending a life span of the NVM and reducing write operation energy consumption.

Dependent claims

A storage space management method, comprising:

obtaining an image feature of data to be written into a non-volatile memory (NVM);
identifying a first image feature that is most similar to the image feature of the data in a feature set of storage space of the NVM, wherein M image features obtained according to M idle blocks in the storage space of the NVM are comprised in the feature set, wherein a size of each idle block in the storage space is equivalent to a size of the data, wherein the M idle blocks comprise an invalid data block and an area in which no data is written in the storage space of the NVM, and wherein M is a natural number;
and
writing the data into an idle block having the first image feature.

A storage space management apparatus, comprising:

a receiver configured to receive data to be written into a non-volatile memory (NVM);
a processor coupled to the receiver and configured to:
obtain an image feature of the data to be written into the NVM;
identify a first image feature that is most similar to the image feature of the data in a feature set of storage space of the NVM, wherein M image features obtained according to M idle blocks in the storage space of the NVM are comprised in the feature set, wherein a size of each idle block in the storage space is equivalent to a size of the data, wherein the M idle blocks comprise an invalid data block and an area in which no data is written in the storage space of the NVM, and wherein M is a natural number;
and
write the data into an idle block having the first image feature.
