Using serial eeprom to save data ?

11 bytes ( 88 bits)

10,000 students @ 11 bits each = 88,000 bits.
Dealing with 11 bits isn't worth the pain, so call it 16 bits, in other words, 2 bytes.

Well, I did say that I didn't even need a calculator....RIGHT? I could've SWORE that it said 11 bits...

Nonetheless, the idea still remains...
Except now the address pins on the 24LC256 might have to be used to put 4 of them on the same PCB.
Or use I2CRead/Write with 2/3/4/5 different sets of pins to address the individual chips.
Still not much of an issue is it?

thanks alot for your information which help me very much , but I want to ask what about using usb stick flash disk I think it's a powerfull idea which it's easy to remove it and connect to PC to save data then connect to PIC to make interface for reading and writing in a quick manner, but how ?
