There are different kind of EEPROMs. Do you have any specific in mind? How about interfacing? Like I2C? Or SPI?
Please take a look at a couple of EEPROMs to get an idea:

Also, specify what do you mean by Atmel microcontrollers. I assume that, in this case, you are referring to 8051 series microcontrollers (as is usually the case when someone refers to "ATMEL microcontrollers"). But specify it, since Atmel also makes "AVR"s and "ARM"s.

I mean interfacing of 24c64 eeprom with atmega8 (or ) atmega32, by through i2c protocol
I need code,

Which compiler are you using?
Implement I2C with the TWI module in the ATMEGA 8/32. If you need ready-made code and don't want to learn how to do it yourself, google it - you can find lots of codes.
