Figure 5 illustrates a typical memory connection for a system using a 128kB SRAM. Note that in this
configuration, both program and data are stored in a common RAM chip Figure 6 shows a similar system
with using two 32kB SRAMs. The byte-wide address bus connects to the SRAM address lines. The
bidirectional byte-wide data bus connects the data I/O lines of the SRAM.
