Passing a shell parameter to awk

Hi:
please, how can I pass a shell parameter to an awk command ?

>cat script
memory=3D20480
value=3D1380
echo $value | awk =B4{ calc=3D$memory-$1*8192/1024/1024}=B4

Thanks.

echo $memory $value | awk '{print $1 $2}'

the variable $memory will pass as $1 and $value will be pass as $2 in awk.

echo $value | awk -v m=3D$memory '{ calc=3Dm-$1*8192/1024/1024}'
