Hello,

That depends.
Look at the pin configuration, when the same pins are used for the addresses,
and there is an extra addres pin on the 256 M chip, it shall not be a great problem.
Just connect the extra pin to ground and you will have a 128 M chip.

there are different types of ram like ddr1,ddr2,....
you can only match a ram of same type.
you take care on the type of ram.
