This direct interface ensures that the host CPU (such as the CPU 771 or CPU 772) can scale its registers, local variables, and memory-intensive I\/O density configurations without experiencing communication bus bottlenecks. To secure the expanded data space, the memory utilizes the host module's battery-backed structure and executes continuous CPU checksum routines to verify memory block integrity during active cycles.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does the installation of the IC697MEM717 require a separate slot in the Series 90-70 rack?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e No. The IC697MEM717 is designed as a direct-attach daughterboard expansion module that mounts directly onto the host CPU or PCM board, leaving all physical chassis slots free for I\/O modules.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How is data preserved on this memory module during a total power failure?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Data retention is maintained by the battery-backup circuitry located on the host CPU or PCM module.
