Why 256 x 8 memory chips is require to design 2k x 8 memory, Computer Engineering

Assignment Help:

A number of 256 x 8 bit memory chips are available. To design a memory organization of 2 K x 8 memory. Identify the requirements of 256 x 8 memory chips and explain the details.

Ans:
Chips available=256x8

Required capacity=2048x8

Number of chips=(2048x8)/(256x8)=8

=(256=2⁸)

For 2048x8chip address lines required =11(2048=2¹¹)

Hence the size of the decoder=3x8.
