Abstract

The invention discloses a data migration method, a memory and a controller, and belongs to the technical field of computers. The data migration method comprises the following steps: receiving a data migration instruction sent by a controller; and in response to the data migration instruction, according to a source address, a destination address and a target data volume in the data migration instruction, migrating target data which is stored by taking the source address as an initial address and has the data volume of the target data volume to a region which takes the destination address as the initial address for storage.

Description

technical field [0001] The application belongs to the technical field of computers, and in particular relates to a data migration method, memory and controller. Background technique [0002] like figure 1 As shown, the existing method for migrating data from the source address of the memory to the destination address includes the following steps: Step 101, the controller sends a read command to the memory, and the read command carries the data amount and source address of the first target data ; Step 102, the controller reads the first target data from the memory based on the data amount and source address of the first target data; Step 103, the controller edits the first target data to obtain the second target data; Step 104, control The device sends a write command to the memory, the write command carries the second target data and the destination address, and takes the destination address as the starting address to write the second target data in the memory; step 105, af...
