摘要: Change bits are provided in correspondence with storage information units (blocks or pages) of a storage, and indicate whether not "store" operation has been performed into the corresponding units. The change retained first retention device units, copy is second device. When store to effect storing data control refers bit by controls updating accordance indication referred to.
