In a design I can see different memories with same width and depth having different mux options
for example 1024x32 with mux option 8(rf1024x32m8) and 1024x32 with mux option 4.(rf1024x32m4)
what exactly does mux option mean in a memory?
does these memories have any difference in functionality(on system level)?
In reply to s_vishnu:
Memories layouts are usually squarer for efficiency. For example your 1024x32 memory might be laid out as 256 rows by 128 columns. Then you would 32 4:1 muxes to select your 32-bit result. Bit it were 128 rows by 256 columns, you would ned 32 8:1 muxes. I’m assuming the mux option is this ratio, but you should check with the memory IP provider to be sure.
