Later versions of the CRAM; 353-2 and 353-3 used Decks of 512 card, thus doubling the storage capacity of each unit. The CRAM was also available on NCR's third generation NCR Century 100 as the NCR/653-100. Each card contains seven tracks containing 1550 slabs each of them. Normally the track was initialized with a four slab header containing the cartridge number (2), the card number and the track number.
