Top of page, first diagram

The diagram at the top of this page is meant to show how two 8x1 RAM arrays can form a 16x1 RAM array. The problem is that the diagram does not show this.

The DATA IN line is wired into a 1-to-2 decoder, so the outputs from the decoder would presumably be DI and DI-bar. The problem with this is that the WRITE line is connected directly to each of the two 8x1 RAM arrays.

The result of this would be that when you attempt to write a value to one 1x8 RAM array, you also write the opposite value to the corresponding line on the other 1x8 RAM array. The two arrays would be mirror images of each other, rather than holding 16 distinct bits of data.
