Memory to Memory Instructions was popular in the 60s and 70s with PDP-8 and PDP-11 ISA. The most recent one I know is VAX-11 ISA that uses their instructions.
They are slow but operate directly on the physical memory, therefore, are simpler to understand.
For reference, you can look up the Instruction Manual for DEC PDP-11 or DEC VAX-11/780.

Agree with the answer Have both their operands in the main store.

Main store refers to main mamory. So both the operands are in main 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.
For example:
I1: PUSH B.
I2: PUSH X.
I3: ADD.
I4: POP C.
Output is C = B+X.

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

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