You have been assigned to design a 16M Byte memory board out of 256K Byte chips.

Each time an access is made to the memory two bytes are returned. Thus, the memory is half-word

addressable. Each of the 256 KB chips is byte addressable. Assume address multiplexing is not used

(Similar to the example in slide 4/22. Use the example in slide 4/22 as a guide to answer the following

questions:

a. How many bits are required in MAR?

b. How many chips are needed to build the memory?

c. What is the size of the decoder (X by Y)?

d. How many rows of chips are needed to build the memory?

e. What is the capacity of each row (i.e., the number of bytes in each row)?

f. What is the MBR size (i.e., number of bits in MBR) for the overall memory?

Answer rating: 100% (QA)

a To determine the number of bits required in the memory address register MARwe need to calculate the total addressable spaceSince each memory access retrieves two bytesthe total addressable space is ... View the full answer
