I guess there are different kinds of instruction format this storage to storage type.

There are several instruction types in memory to memory instruction type both operand is in memory and result is also available in memory.

In CPU classification we have Stack CPU. In stack CPU both the operands are present in the stack memory and after ALU operation are further kept the output in the stack memory. So it use storage to storage instruction.

For example:

I1: PUSH B.
I2: PUSH X.
I3: ADD.
I4: POP C.

Output is C = B+X.

Main store refers to main mamory. So both the operands are in main memory.
