    Hello

    Data memory

    Data memory is used to read and write data

    Example

    Code (Text):
    1.  
    2. Address       Data
    3.  
    4. 1                     10
    5.  
    6. 2                      12
    7.  
    8. 3                       14
    9.  
    10. 4                      16
    11.  
    Load the data from memory address 2 and save into A register ( read data from memory)

    Store data from A register to memory address 3 (write data to memory

    Suppose

    Data memory specification

    Address bus 2 bit

    Data bus 4 bit

    Accumulator register

    How to make data memory? how many address and data register I have to use in data memory ?

    You could do it the hard way, using data latches; or you could (more cheaply), just buy a memory IC.
    Anything from 1 (a 1-bit latch or register) to a gazillion googabytes. That's a bit like asking "How long is a piece of string?". Or were you referring to the 2 bit/4 bit example?
