Abstract
A computer system with programmable serial presence detection (SPD) data is disclosed. The computer system uses a user-programmable memory to store virtual SPD data which includes the configuration information of the memory module. The virtual SPD data is stored separately from the system boot code of the computer system. A computing unit uses a memory driver to drive the memory module. The memory driver accesses the user-programmable memory through a virtual SPD module to acquire the configuration information of the memory module.
Claims20
A computer system with programmable serial presence detection (SPD) data, comprising:
- a memory module;
- a user-programmable memory, storing virtual SPD data which includes configuration information for the memory module, wherein the virtual SPD data is stored separately from the system boot code of the computer system;
- and
- a computing unit, using a memory driver to drive the memory module,
- wherein:
- the memory driver accesses the user-programmable memory through a virtual SPD module to acquire the configuration information of the memory module, and the virtual SPD module uses a memory mapping input/output technique to get an address and reads the user-programmable memory to acquire the virtual SPD data stored at the address.
(canceled)
A control method for a memory module, comprising:
- storing virtual SPD data in a user-programmable memory, wherein the virtual SPD data includes the configuration information of the memory module, and the virtual SPD data is stored separated from the system boot code of the computer system;
- and
- using a computing unit to execute a memory driver to drive the memory module, wherein the memory driver accesses the user-programmable memory through a virtual SPD module to acquire the configuration information of the memory module,
- wherein the virtual SPD module uses a memory mapping input/output technique to get an address, and reads the user-programmable memory to acquire the virtual SPD data that is stored at the address.
