“How do I copy a serial EEPROM chip?” is the most common question ask by people.Inside the Computer motherboard , some radios , same car keys , Mobile phones and many other electronic devices can found Serial EEPROM memory chips. Most of the time in Serial EEPROM memory chips have 8 pin and retain data when the unit is switched off, which is why they are used for settings and configuration data. This is the reason for peoples need to copy data from Serial EEPROM memory chips. EEPROM copier circuit diagram
So, following you can see the away of copying a serial EEPROM?
First of all we must identify about serial EEPROM chips. There are many different types of serial EEPROM chip and the chip types. All of EEPROMs are used to same method for storing data inside the chips. but The communication of EEPROM are different various each and every chip family. So, We can identify main three types of serial EEPROM chip used in commercial products. They are as follows.EEPROM copier circuit diagram
In here, It is not necessary to know about about these protocols the reason for that is serial EEPROM chip programmer will deal with this protocols. However, it is necessary to read the chip number of EEPROM from the top of the chip. EEPROMs has many numbers with the data codes. However, the important one has 24, 25 or 93 in it. Most of the time the chip number is start with the letter for manufacturer such as AT for Atmel, M for STM etc.
Some examples for chip numbers -:

Most of the time you do not need to too much worry about the EEPROM series or manufacturer of the chip because of the devices of most manufacturer are same. If you buy similar EEPROM devices from different chip manufacturer the program the chip and chip reading ways are same as long as you choose one from same family 24, 25 or 93 with same memory size.
If you are remove chip from the he circuit board, To include the program into chip, You have to put into socket programmer or Socket reader.save the made contents in of the chip and program new devices. Many common universal programmers support serial EEPROM chips. Therefore It is not necessary to buy expensive product for them
The following universal programmer can be used to read and write EEPROM chops as well as It can buy you same small price.
If your serial EEPROM is not a DIL package and is surface mount eg SOIC, then you will need a socket adapter as well.
