Abstract: This application relates to the field of memory technology, in particular to a method and a system for remapping a row address on a multichannel DIMM. The method is applied to a memory controller, comprising: receiving a first read/write access address and extracting a first channel row address from the first read/write access address; encrypting and mapping the first channel row address through a key-based mapping method to obtain a second channel row address that corresponds to the first channel row address within a predetermined address range; forming a second read/write access address based on the second channel row address and unextracted address information in the first read/write access address, and performing read/write access to the DIMM based on the second read/write access address. The present application can alleviate side channel attack without causing degradation of read/write performance.
