Abstract: A memory address remapping method is disclosed. The memory address remapping method comprises: providing a cache-related address having a tag, an associative tag, a set index and a block offset; providing a linear operator; performing a linear calculation with a first linear operator input and a second linear operator input to obtain a first output, wherein the first linear operator input is several bits picked from the set index of the cache-related address according to a quantity and a corresponding location of a plurality of bits in the location address of a memory address, such as DDR memory-related address, Rambus memory-related address, etc.
