Mass memory device and method for operating a mass memory device

摘要

A mass memory device ( 1 ) having a plurality of mass memories ( 2 ) and having at least two bridge controllers ( 3 ) which are coupled to the mass memories ( 2 ) by a data bus. A first common cache memory unit ( 4 ) is provided, to which the bridge controllers ( 3 ) are connected by means of an additional cache synchronization system for the purpose of storing and synchronizing data which are to be stored. A method is provided for operating a mass memory device ( 1 ) having a plurality of mass memories ( 2 ) and having at least two bridge controllers ( 3 ) which can be used to address the mass memories ( 2 ), and at least one first common first common cache memory unit ( 4 ) which is associated with the bridge controllers ( 3 ). All data to be stored are initially stored on the first common cache memory unit ( 4 ) and are automatically mirrored on an optional further common cache memory unit ( 4 ). The data initially stored in the first common cache memory unit ( 4 ) are transferred to the mass memories ( 2 ) for storage therein.
