System Management Mode - (SMM) A reduced power consumption state provided by some Intel microprocessors. When a CPU enters SMM it saves its current state in a special area of static RAM called SMRAM (System Management RAM) and then runs a program, also stored in SMRAM, the SMM handler.

SMM is implemented in all Intel "SL" suffixed CPUs. In June 1993, Intel announced it was discontinuing its SL range and instead making all its current processors SL enhanced.
