Think of this device as the home router behind yourcable, DSL or FIOS modem. It is desirable to store at least256 IP addresses and port numbers, each requiring about 32 bytes ofinformation. Contrast at least two of the options for thememory technology that might be employed for this access logstorage: static CMOS RAM, dynamic MOS RAM, Flash,electrically alterable ROM or mask programmed ROM.
