Nortel Networks 1000 - Manual (Page 895)

Functional description 895
The shared memory is the interface between the CS 1000 CPU and the
68EC020 MPU. This memory is a 16 Kbyte RAM, expandable to 64 kbytes
and accessible in 8 or 16 bits.
EPROM memory
The Bootstrap code resides in this 27C1000 EPROM and is executed on
power up or reset.

Flash EPROM memory
Flash EPROM provides non-volatile storage for the DDCH loadware which
minimizes the impact to sysload. The Flash EPROM provides an increase
in system service with a reduced delay after a brown-out, and faster
testing of a hardware pack after it is plugged in.

EEPROM memory
The DDCH uses a 1024 bit serial EEPROM for storing the Nortel product
code and a revision level. This information can be queried by the software.
The DDCH uses a 1,024 bit serial EEPROM for storing the NT product
code and a revision level. This information can be queried by software.
