Choose an address HA0

with HA0[13] = 1

Choose an address HA0

with HA0[13] = 0

Define addresses as follows

HA1 = HA0 & HA0 [25,24,20,12,11,10]=000000

HA2 = HA0 & HA0 [25,24,20,12,11,10]=100100

HA3 = HA0 & HA0 [25,24,20,12,11,10]=000010

HA4 = HA0 & HA0 [25,24,20,12,11,10]=010000

HA5 = HA0 & HA0 [25,24,20,12,11,10]=000001

HA6 = HA0 & HA0 [25,24,20,12,11,10]=001000

Memory Write : Address = HA1 with Data = D1

Memory Read : Address = HA1 with Data = D2
