Okay so I know when I need to build a parallel design I can put them near each other and make a 4k*8 to expand the databus. But on this one I only need to use half of them and the databus length is larger than my total chips can reach. But I thought 2k*12 requires 24k b of data and i have 32k of space to store data. So there has to be a way to do so.
When I use a parallel design I can reach 4k*8 but it is not enough.
