Capacity of RAM Chip = 1k*8 bit
MEMORY CAPACITY = NUMBER OF CHIP * ONE RAM CHIP CAPACITY
Number of chip = memory capacity / one chip capacity
# chip =16k * 16bit / 1k * 8bit
# chip =(16 * 2 ) = 32 chip ➔➔➔ (16 * 2 ): Meaning is there are 16 Rows , where 2 chips in each rows .
so,we could required (4 * 16) Decoder , Now get ( 4* 16) Decoder using ( 2* 4) it would be like below…
so the number of decoder of size(2*4) is 5
