#16371 - How to write into AT28c64

Hi,
Does anyone know how to program/write EEPROM AT28c64?
I use basic command like :
...
Mov dptr,#EEPAdd
mov a,#75H
mox @dptr,a
lcall delay1ms ; 1 ms delay
..
to write to EEPROM, but i can only write 2 from 12 times of writing. EXAMPLE :
if I write from address 0000 to 0020h
it become :
75 FF FF FF FF FF 75 FF FF FF FF FF 75

after second until sixth are empty.

Anyone have the sample code that i can use ?
