The UltraRAM supports dynamic power gating (sleep) modes for power savings when there is no access activity. The EN_AUTO_SLEEP_MODE attribute enables automated sleep mode by predicting the activity of many cascaded UltraRAM blocks, or the SLEEP input port can be asserted to explicitly put an UltraRAM into a sleep mode. Although the OREG_[A|B] output registers are reset when in sleep mode, the UltraRAM retains its data. SLEEP allows a two clock-cycle wake-up time.
