US Patent 7313732 Memory arrangement in a computer system

A memory arrangement in a computer system can have at least one memory module with semiconductor components, which are arranged on the memory module, can be operated in parallel and are additionally connected to one another via a serial line. The memory arrangement can have an interface bus for driving the semiconductor components on a module-specific basis, and an interface, which is driven by a memory controller assigned to the memory module via the interface bus and accesses the semiconductor components via the serial line. During normal operation, it is possible to test and adjust the semiconductor components in proximity to the application and on a chip-specific basis via the interface.
