System and method for memory access dynamic mode switching

摘要

Systems, methods, and other embodiments associated with providing dynamic switching between memory access modes are described. According to one embodiment, an apparatus includes first memory and second memory. The apparatus also includes a memory control logic configured to facilitate memory access of the first memory and the second memory using either a first memory access mode or a second memory access mode. The first memory access mode is configured to facilitate memory access of both the first memory and the second memory. The second memory access mode is configured to facilitate memory access of one of the first memory or the second memory. The memory control logic is configured to dynamically switch between the first memory access mode and the second memory access mode, without having to remap memory or reboot the system, in accordance with a region-based memory address mapping technique.

主权项

1. An apparatus comprising:
first memory; second memory; and memory control logic configured to facilitate memory access of the first memory and the second memory using either a first memory access mode or a second memory access mode,
(i) wherein the first memory access mode is configured to facilitate memory access of both the first memory and the second memory,(ii) wherein the second memory access mode is configured to facilitate memory access of one of the first memory or the second memory, providing less performance and using less electrical power than the first memory access mode, and(iii) wherein the memory control logic is configured to dynamically switch between the first memory access mode and the second memory access mode, without having to remap memory or reboot the apparatus, in response to an address of a memory access command and in accordance with a region-based memory address mapping technique which associates regions of memory with the first memory access mode or the second memory access mode.
