EEPROM Market Issues • Suppliers are not notified of potential problems! • Maxwell is committed to supply product that meets your needs – no exceptions • Improvements in product screening can only occur based on failure evaluations • Product failures must be evaluated! • Most problems are never verified – no resolution • Perception becomes reality – not supported by data • Proper application is important! • Proper control of RESET input is required to prevent data corruption • Proper programming is required to ensure error-free operation
Conclusion • Hitachi 1Mb EEPROM is conservatively specified • All data retention/programming problems can be eliminated by proper screening • Date Retention not degraded by TID • Endurance not degraded by TID • Proper system design provides a very reliable solution for space • EEPROM enables reliable, reconfigurable systems
