ABSTRACT:
In a memory hierarchy system comprising a main memory for storing data and a buffer memory for holding a part of the data stored in the main memory as a copy of the main memory data, the data on the buffer memory is frequently replaced by the data on the main memory so as to hold in the buffer memory the data which is very frequently used. The buffer memory also holds the data which is in an area of the main memory where an irremediable fault occurred and that data is prevented from being replaced. Therefore, the buffer memory is substituted for the fault area of the main memory so that a fail soft system is attained.
