A $3\times 8$ decoder with $2$ enable inputs is used to address $8$ block of memory. What will be the size of each memory block when addressed from a $16$ bit bus with $2$ MSB’s used to enable the decoder?

A $3 \times 8$ decoder with two enables inputs is to be used to address 8 blocks of memory. What will be the size of each memory block when addressed from a sixteen-bit bus with two MSBs used to enable the decoder? $i)2k$ $ii)4k$ $iii)16k$ $iv) 64k$ What does “two enable inputs is to be used” mean? I am not able to visualize the circuit.

A $3$ line to $8$ line Decoder is used to implement a $3$-variable Boolean function as shown in figure. The simplified form of output $Y$ is. $\bar{X}Y + \bar{Y}Z + XY\bar{Z}$ $\bar{X}Z +\bar{Y}Z + XYZ$ $X\bar{Y} + X\bar{Z} +\bar{X}YZ$ $X\bar{Y} + X\bar{Z} + \bar{X}Y\bar{Z}$
