Could you explain this problem. Pls give me explanation for the steps.

More on Chip Organization

$$Preceding $16$x$8$ chip has only $128$ storage cells

$$With power$/$ground$,$ need $4+8+2+2=14$ pins

$$Larger chips: similar organization, more pins

$$For example, a chip with $1024$ cells could be

organized as $128$x$8(7+8+2+2=19$ pins$)$ or

alternatively as $1024$x$1(10+1+2+2=15$ pins$)$

$$Pin count dictates cost, so consider $1024$x$1$

$$Use $32$x$32$ array & divide address bits to have

$5$ upper bits for row, $5$ lower bits for column
