Abstract
Systems and methods for reducing heat flux in memory systems are described. In various embodiments, heat flux reductions are achieved by manipulating the device IDs of individual memory devices that comprise a memory module. Through the various described techniques, the per-face heat flux can be desirably reduced. Further, in some embodiments, reductions in heat flux are achieved by providing control lines that operably connect memory devices on different faces of a memory module.
Claims42
A power management method comprising:
- providing one or more memory modules each comprising one or more faces, multiple channels on one or more of the faces, multiple memory devices on each channel, the memory devices being configured for operation in lock-step;
- and
- assigning device IDs for each device, the device IDs being arranged so that power dissipation per face is minimized.
A power management method comprising:
- providing one or more memory modules each comprising one or more faces, multiple channels on one or more of the faces, multiple DRAM devices on each channel, the DRAM devices being configured for operation in lock-step;
- and
- assigning device IDs for each DRAM device, corresponding DRAM devices on different channels having the same device ID, the device IDs being arranged so that no two DRAM devices have the same device ID on any one face.
A power management method comprising:
- providing one or more memory modules each comprising one or more faces, multiple channels on one or more of the faces, multiple DRAM devices on each channel, the DRAM devices being configured for operation in lock-step;
- and
- assigning device IDs for each DRAM device, corresponding DRAM devices on different channels having the same device ID, the device IDs being arranged so that the physical distance between corresponding devices is maximized.
A power management method comprising:
- providing one or more memory modules each comprising one or more faces, multiple channels on one or more of the faces, multiple memory devices on each channel, the memory devices being configured for operation in lock-step;
- and
- assigning device IDs for each memory device, corresponding memory devices on different channels having the same device ID, wherein there are enough memory devices so that at least one pair of corresponding devices have to appear on the same face of a module, the device IDs being arranged so that the physical distance between corresponding devices on a face is maximized.
A power management method comprising:
- providing a memory module comprising front and back faces, and multiple devices on each face;
- and
- connecting devices on each of the faces with a control line so that the connected devices commonly contribute multiple bits to a data bus.
