The supports either Flash Memory or ARAM/DRAM as external memory for storing
messages. If ARAM/DRAM is used, an EPROM can be added optionally to support read-
only messages (e.g. voice prompts).
Note: Although the memory accesses are performed by the , the specification of the
Table 96 summarizes the different configurations supported.
Table 96
If ARAM/DRAM is used, the total amount of memory must be a power of two. If more
than one memory device is used, the memory devices must be of the same type.
For flash devices, voice prompts do not need to be programmed via the PSB 4860. They
can also directly be programmed by any other circuitry into the Flash. This is supported
