Memory module, e.g. for use in computer systems, with number of integrated memory components has separate access control circuit that generates column and row addresses from memory access addresses

摘要

The device has a carrier substrate (50) with connections (40) for feeding address and command signals, integrated memory components (10-18;20-28) on the substrate and a separate access control circuit (30) on the substrate with inputs connected to the connections for feeding address and command signals and outputs to the integrated memory components. The access control circuit generates column and row addresses (CADR,RADR) from memory access addresses.
