Abstract
Memory modules without signal-conditioning devices (unbuffered, unregistered) are provided in a system by using adapter cards that have signal-conditioning devices and are then operated in the manner of memory modules with signal-conditioning devices (buffered, registered). Systems can thereby be expanded in a very simple manner and can be flexibly adapted according to requirements, and for this purpose only one type (unbuffered, unregistered) of memory module is required.
Claims10
A method for operating a plurality of memory modules, which do not have signal-conditioning devices, and at least one memory module, which has a signal-conditioning device, on slots of a system, the method which comprises:
- providing a system motherboard having the slots of the system;
- providing at least one adapter card having plug-in sockets and a signal-conditioning device;
- configuring the plurality of the memory modules, which do not have signal-conditioning devices, in the plug-in sockets of the adapter card;
- providing the adapter card on one of the slots of the system;
- providing a memory module, which has a signal-conditioning device, on another of the slots of the system;
- and
- operating the plurality of the memory modules, which do not have signal-conditioning devices, in the system as memory modules having signal-conditioning devices.
An adapter card for operating at least one memory module, which does not have a signal conditioning device, on a slot of a system, comprising:
- a substrate;
- at least one plug-in socket for accommodating said memory module that does not have a signal conditioning device;
- an interface compatible with the slot;
- and
- a signal-conditioning device for operating said memory module, which does not have a signal conditioning device, in said plug-in socket as a memory module having a signal-conditioning device, said signal-conditioning device including a DQ buffer for the signal-conditioning of data signals and a CA buffer for the signal-conditioning of control and address signals.
