8-pin microchip help

Edit: Nevermind, I saw that you put the numbers in the OP.

I want to know how to read a 8-pin mircochip it has no company name to it so how do i read the chip and how do i rewrite anything on it thank .
numbers on the chip: there are 3 lines of numbers/letters
1.ATMLU814
2.01B
3.77G2069E

Hard to find a datasheet for that chip, but you can contact the ATMEL vendor for a datasheet for that part, or get any DIP 8 ATMEL datasheet(to get a basic schema for it), and using some some standard ATMEL instruction sets(you would not know its full capacity but you would know its standard stuff).

You can use a standard atmel programmer, or you can create your own programmer(but I suggest you buy one since it costs 15$ a new programmer), for reading and writing.

But I suggest going to the nearest electronics shop, or you can order on the net some Atmel/Microchip/ARM chips where you can find datasheets for it.

ok thanks ghost107

Since this chip is a memory module (not a micro-controller, does not have instruction set).

So as Documentation take a look at this chip:
http://www.atmel.com/devices/AT24C16B.aspx?tab=overview

According to part marketing in the documentation:
ATMLU814 (ATML = ATMEL, U =8-PDIP , 8 = 2008, 14 = week 14)

ok ghost tell me this plz
:do i get the programmer of that site
:if so whats the programmer product name so i can buy it

He clearly said it has no instruction set. How in the world would you program without any words to program with? It's like attempting to get a blind, deaf, mute, and mentally challenged child to communicate. It. Won't. Happen.

Just curious, how do you know it's not a micro controller? Atmel makes 8 pin micro controllers and if all you know from the code is that it is 8 pin dip and the date, how can you differentiate it from one of the micro controllers and the memory module you posted.

Sorry this is the EXACT document and it still is a MEMORY MODULE(the documentation for this and the previous are the same, but the difference is this module has 1k size while the previous has 16k size):
http://www.atmel.com/devices/AT24C01B.aspx?tab=overview

1.ATMLU814
2.01B
3.77G2069E

As I said ATMLU814(ATML = Atmel, U = 8PDIP, 8 = 2008, 14 = week 14), 01B = device(AT24C01B), 77G2069E is the lot number
An atmel Micro-controller has something else written on it(more info here):

For more info it sais:

The Atmel 1 Kbit two-wire serial EEPROM with full memory write-protect, supports up to eight devices on a single two-wire bus. The EEPROM is organized as 128 words x 8 bits. Optimized for industrial and commercial applications where low-power and low-voltage operations are essential. The EEPROM is available in space-saving packaging options, and 1.8V (1.8V to 5.5V) versions.
