Overview

The N34C04 is a 4-Kb Serial SPD EEPROM for DDR4 DIMM, which implements the JEDEC JC42.4 (EE1004−v) Serial Presence Detect (SPD) specification for DDR4 DIMMs and supports the Standard (100 kHz), Fast (400 kHz) and Fast Plus (1 MHz) I2C protocols.

One of the two available 2−Kb EEPROM banks (referred to as SPD pages in the EE1004−v specification) is activated for access at power−up. After power−up, banks can be switched via software command. Each of the four 1−Kb EEPROM blocks can be Write Protected by software command.

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
