Abstract
In a buffer memory, a validity flag to be added to each data portion is stored in a tag array or address section at a location corresponding to each data portion. After determining whether each validity flag is to be used as a search object, based upon the data portion to be accessed during searching the tag array and an access mode, the address and its validity flag are simultaneously searched. The logical sum of each output of the search result on a word coincidence line becomes a hit judgement signal.
