Selectively supporting different memory technologies on a single motherboard
A motherboard may be adapted to selectively implement one of two different memory technologies. For example, the motherboard may be able to subsequently implement a subsequently developed memory technology. In some embodiments, the motherboard is capable of detecting whether a memory module is in a slot dedicated to a first or a second memory technology and, based on the presence of a memory module in an appropriate slot, the motherboard may be adapted to operate with the particular, selected memory technology.
1. A method comprising:
providing a motherboard with a slot for a first memory technology and a slot for a second memory technology;
detecting a memory module in one of said slots;
enabling a memory controller to be selectively adapted to one of two different memory technologies; and
prohibiting a boot of said motherboard when a memory module of said first memory technology and a memory module of said second memory technology both are present in said slots.
2. The method of claim 1 including providing dedicated slots for each of the two different memory technologies.
3. The method of claim 2 including enabling the motherboard to detect when a memory module is placed in one of said slots.
4. The method of claim 1 , wherein prohibiting said boot comprises disabling a circuit.
5. The method of claim 4 , wherein disabling said circuit comprises disabling a voltage regulator on said motherboard.
6. The method of claim 5 including disabling a voltage regulator for said motherboard when neither of said slots have memory modules in them.
7. The method of claim 1 including providing a different supply voltage to said motherboard depending on the type of memory technology being used.
8. A motherboard comprising:
a first slot for a first memory technology;
a second slot for a second memory technology;
a memory controller hub adaptable to one or the other of said memory techno 1 ogies; and
a circuit to prevent a boot of said motherboard when both a memory module of said first memory technology is present in said first slot and a memory module of said second memory technology is present in said second slot.
9. The motherboard of claim 8 wherein said first slot is a first dedicated slot to only receive a memory module of said first memory technology and said second slot is a second dedicated slot to only receive a memory module of said second memory technology.
10. The motherboard of claim 9 including a circuit to detect that a memory module is placed in one of said slots.
11. The motherboard of claim 10 including a memory controller, wherein said circuit to prevent said boot disables said memory controller when a memory module is placed in both of said slots.
12. The motherboard of claim 11 including a voltage regulator, wherein said circuit to prevent said boot disables said voltage regulator when a memory module is placed in both of said slots.
13. The motherboard of claim 12 wherein said voltage regulator is disabled when neither of said slots have memory modules in them.
14. The motherboard of claim 8 including a memory controller and a voltage regulator, said voltage regulator to supply a supply voltage to said memory controller depending on the type of memory technology being used.
15. A motherboard comprising:
a first slot for a first memory technology;
a second slot for a second memory technology, wherein said first slot is a first dedicated slot to only receive a memory module of said first memory technology and said second slot is a second dedicated slot to only receive a memory module of said second memory technology;
a memory controller hub adaptable to one or the other of said memory technologies; and
a voltage regulator, said voltage regulator to be disabled when a memory module of the first memory technology is present in the said first slot at the same time a memory module of the second memory technology is present in said second slot.
16. The motherboard of claim 15 including a circuit to detect that a memory module is placed in one of said slots.
17. The motherboard of claim 16 wherein said voltage regulator is disabled when neither of said slots have memory modules in them.
18. The motherboard of claim 15 including a memory controller, said voltage regulator to supply a supply voltage to said memory controller depending on the type of memory technology being used.
