8 bit Electrically Erasable PROM
(based on Serial Presence Detect)
BR34L02FV-W
The BR34L02FV-W is a 2k bit EEPROM memory with write-protect function having independent rewrite inhibit area,
developed for a DIMM that uses synchronous DRAM memory, and a RIMM that uses RAMBUS DRAM memory. This is
a memory IC that reads ID in order for the Plug & Play feature to operate.
