Apparatus and method for accessing non-overlapping portions of memory according to respective orders of dimensions

摘要

A system including a storage device and a controller. The storage device is configured to store a map. The map relates (i) a first portion of a memory to a first order of first dimensions, and (ii) a second portion of the memory to a second order of second dimensions. The first portion of the memory and the second portion of the memory are non-overlapping. Each of the first dimensions and each of the second dimensions has corresponding memory cells in the memory. The controller is configured to control access to the first portion of the memory according to the first order of first dimensions while controlling access to the second portion of the memory according to the second order of the second dimensions.
