NV34C04 Datasheet | onsemi

Description The NV34C04 is a EEPROM Serial 4- Kb, which implements the JEDEC JC42.4 (EE1004- v) Serial Presence Detect (SPD) specification for DDR4 DIMMs and supports the Standard (100 k Hz), Fast (400 k Hz) 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 mand. Each of the four 1- Kb EEPROM blocks can be Write Protected by software mand.
