Abstract
A memory controlling apparatus is provided with: a record information memory, a vacant address controller for serially storing the address data which specifies the addresses where record information referred to has been stored in order of reference, supplying the address data in the order of storage, and designating the addresses for storing the record information on new events by the supplied address data; and a LRU (least recently used) unit for storing the address data; and a LRU unit for storing the address data which specifies the address of the memory at which record information is stored in the order of storage. When a new event occurs, a control unit obtains the address at which the oldest record information is stored from the LRU unit, if no address is designated by the vacant address controller, and stores the record information on the new event at the address obtained, while storing the record information on the new event at the designated address when the address is designated by the vacant address controller.
