M34E02, M34E02-F 2 Kbit serial presence detect (SPD) EEPROM for double data rate (DDR1 and DDR2) DRAM modules. It features 100 kHz and 400 kHz I2C bus serial interface, byte and page write, and self-timed write cycle.
The M34E02 and M34E02-F are 2 Kbit serial EEPROM memories specifically designed for use in DDR1 and DDR2 DRAM modules with serial presence detect (SPD). These devices allow the storage of information concerning the DRAM module configuration, such as access speed, size, and organization, within the first half of the memory.
