2.3 MEM3 AND MEM4 CARD
To operate, the KSU must be equipped with an iDCS 100 MEM3 or an iDCS 100 MEM4
card to hold the system software and customer database. The software is stored in EPROM
chips for the iDCS 100 MEM3 card and in Flash Memory on an iDCS 100 MEM4 card. All
specific customer data is stored in non-volatile random access memory (NV-RAM). The
MEM3 and MEM4 cards are both protected by a super capacitor providing up to seven
days of memory protection in the event of loss of AC power to the system.
