I have one in an SAP Function Module whose storage space needs to be increased.
It imports the parameter 'memory_key' . Its value is
'DEF_OTF_MEMORY_KEY'.
FUNCTION READ_OTF_FROM_MEMORY.
*"----
""Lokale Schnittstelle:

DATA: MEMKEY(32). "max len of memory id is 32
MEMKEY = MEMORY_KEY.
IMPORT OTF FROM MEMORY ID MEMKEY.
IF SY-SUBRC <> 0.
RAISE MEMORY_EMPTY.
ENDIF.
ENDFUNCTION.
