Abstract
A memory system and method for allocating and accessing memory. The memory system includes first and second addressable memory regions coupled to a memory controller. The memory controller includes a register to store a respective offset value and values defining portions of the first and second addressable memory regions allocated to first and second logical memory spaces. A first portion of the first addressable memory region is allocated to a first requested memory space, and a second portion of the first addressable memory region is allocated to a second requested memory space. Any remaining portions of the first and second requested memory spaces are remapped to the second addressable memory region. The memory controller is adapted to access the first addressable memory region in response to receiving a memory address for a location within the first portions of the first and second memory spaces and to access the second addressable memory region in response to receiving a memory address for a location within the second portions of the first and second memory spaces.
