Abstract
A method for migrating data to avoid read disturbance is introduced to contain the following steps: finding a singular physical-block from physical blocks; performing a test read on data of the ith physical page of the singular physical-block; determining whether the data of the ith physical page of the singular physical-block has passed the test read; and when the data of the ith physical page of the singular physical-block has not passed the test read, moving or copying data of the ith physical page and at least one neighboring physical-page of the singular physical-block to an available physical-block.
