System and method for accessing distinct regions of memory using multiple mapping modes, each of the mapping modes having a predetermined order of dimensions for a respective region of the memory

Abstract

A system including a register and a controller. The register is configured to store a map relating distinct regions of a memory to respective mapping modes. Each of the mapping modes identifies a predetermined order of dimensions of a respective region of the memory. Each of the dimensions of the regions of the memory is identified as a row, a bank, or a column. The mapping modes include (i) a first mapping mode having a first predetermined order of dimensions, and (ii) a second mapping mode having a second predetermined order of dimensions that is different from the first predetermined order of dimensions associated with the first mapping mode. The controller is configured to control access to the distinct regions of the memory according to the map stored in the register, including controlling access to a first region of the memory according to the first mapping mode while controlling access to a second region of the memory according to the second mapping mode.
