Show the cell array organizations for the following memory sizes:

a$.128\backslash$times $1$

b$.64\backslash$times $2$

Guidelines:

$($i$)$ For both parts: use the Row address as $3-$bits.

$($ii$)$ For part $($a$)16$ columns $(4-$bit address$)$ each cell is $1$ bit: $8$ x $16$ x $1$ configuration. At any given time $1$ data bit is onto the data bus.

$($iii$)$ For part $($b$)$ use an $8$ x $8$ x $2$ configuration; use $3$ column bits; $2$ data bits.
