We're currently working on a design with a Z7030 device and we're planning on doing some video processing with it so a 1GB DDR memory would come in handy. Since we're targeting a low power board we considered using LPDDR2 memory modules and have had good experiences with Micron devices. However, Micron only offers two-ranked devices for 8Gb densities and 4Gb density devices have 32 bit data width buses, so there's no way a 1GB memory can be built and interfaced with the Zynq, apparently.
Anyone has come accross the same limitation? Any other vendor you would recommend that would consider selling to companies with low to medium production scales?

Yeah, I already read those posts and pretty much figured out there was no way around that limitation. Devices from ISSI and Winbond have lower densities and clock speeds so I guess we're stuck on 512MB with LPDDR2. Thanks anyway.
