64Mbitx8 is 64MByte capacity/chip, so you need 16 pcs. on a 1GByte module.
64Mx8 is not useable on 2GB modules. In this case, the chip capacity should be doubled to 128MBitx8, (128MByte/Chip)
.. For a roughly module calculation just add 16 chips, a PCB, and some spare parts (depending on final module quality about $2,50). Now add labour cost, equipment, testing, salary, profit and other cost, and you'll have the final but only abstract price on a 1GB module.
I don't understand clearly how to figure out Ram Price above.
Today, " DDR3 1Gb 128Mx8 1333MHz 2.82 2.71 2.82 2.71 2.75 ", so i need take 2.75 x 8 (chips) or anyway else ?
Like this: 2.75 x 8 = 22 => 22$ is the price of DDR3 1Gb 128Mx8
Please help me! I'm really confuse about this hix
