Interfacing i.MX53 to two 4Gb RAM Chips (1GB RAM)

Is it possible to interface the i.MX53 to two 4Gb RAM devices, giving a total of 1GB? The Freescale reference designs use four 2Gb devices to give 1GB of RAM. Is there a reason for this?


Looking through the i.MX53 reference manual and comparing the capabilities to Micron's MT41K256M16HA-125 as an example, I don't see any issues; the data width, number of banks, capacity per chip select, column size, address size and burst length all seem to be compatible. Am I missing something?


Has anyone successfully connected 4Gb devices to the i.MX53?


Thanks for your comments in advance!
