Extended Core Storage (ECS) for the Control Data 64/6600 System has been described in another paper. ECS is a large capacity, word-addressable core memory with block transfer times of from eight to ten words per microsecond after a transfer start-up time of approximately 2 microseconds. ECS memories range in size from 131K to over two million words, and can be shared by up to four 6000 systems. The cost per word of Extended Core Storage is about one-tenth that of Central Memory (CM).
