Abstract

A magnetic bubble memory equipment includes means for receiving address information for a plurality of access requests as a whole, and means for executing address matching operations in parallel for a plurality of addresses. Read-out or write-in command information is fetched for each of the access requests in the sequential order as the coincidence is found in the matching of address and data transfer is sequentially executed in accordance with the command information, thereby to reduce the effective access time for the plurality of the access requests.
