They often contained internal batteries; once the battery died, the data vanished (a process known as "suicide"). The availability of the dl1425bin in modern ROM sets is a testament to the "de-capping" and data-recovery efforts of hardware historians who sacrificed original chips to read the internal bits and ensure these games weren't lost to time.
