Figure 13

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 14

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.
