A method for maintaining vital product data (VPD) contained in an EEPROM (Electrically Erasable Programmable Read-Only Memory) on a field replaceable unit (FRU) of a computer system that has a cache. The method includes maintaining a copy of the VPD in the cache, retrieving the copy of the VPD from the cache upon receiving a read request of the VPD, and, upon receiving a write request to write data to the VPD, writing the data to the copy of the VPD, determining whether the VPD in the EEPROM is in synchronization with the copy of the VPD in the cache, and, if the VPD and the copy of the VPD are in synchronization, writing the data to the EEPROM.
