Question: Using the 74138, design memory decoding circuitry in which the memory block controlled by Y0 is in the 0000H to 3FFFH space. Indicate the size

Using the 74138, design memory decoding circuitry in which the memory block controlled by Y0 is in the 0000H to 3FFFH space. Indicate the size of the memory block controlled by each Y.

Please draw the circuitry and explain the steps, I found an answer online before but it was not correct, the outputs should connect to something(?) I thinki tmight be where the memory is allocated.
