It has a total of 16-pin on the package which will be used to carry both the address as well as the data. The low order address lines are multiplexed with 8-data lines and hence the pin 11 to 19...

This 64KB may be one single IC or can be made using smaller memory IC.  The operations on the memory IC can be a memory read or memory write. We can connect the RD’ or WR’ lines from...

As discussed previously, microprocessor fetches an instruction from the memory, decodes it, fetches the operands if required and then executes the instruction. An execution of a instruction...
