Q2. (a) Figure 2 shows the pinout diagram (and their functional description) of the 2114 Static RAM memory IC. Using a neat sketch show how such IC may be interfaced with an M68000 microprocessor to realise a system that needs 1K x 16 bits of RAM. [Note: 2114 is a 4-bit memory IC. You will need multiple ICs to make up the 16-bit data bus of the M68000 processor.] A6 1 A5 2 18 Vcc 17 A7 Ao-Ag WE CS Pin Names Address Inputs Write Enable Chip Select
