Memory Mode – What is it in Vaping?
Definition
Memory Mode is a user-programmable feature found on advanced vape mods that allows you to save and instantly recall your preferred power, temperature, or wattage settings. Instead of manually scrolling through menus every time you switch MTL (Mouth to Lung) tanks, Coil“>mesh coil sub-ohms, or different e-liquids, you store up to five (sometimes more) complete profiles. One click cycles between “Memory 1” for a cool 12 W MTL draw, “Memory 2” for a warm 65 W mesh burst, and so on. The chip remembers everything—wattage, pre-heat, even boost curves—so your ideal vape is always a button-press away, making device hopping effortless for Australian vapers who like variety.
Technical Details
Internally, Memory Mode writes parameter sets to non-volatile EEPROM inside the mod’s MCU. Each slot records: output mode (VW/TC-Ti/TC-SS), set value (watts or °C), pre-heat level (soft/norm/hard), and sometimes custom power curves in 0.5 s increments. Chips such as the DNA 250C offer eight 250-byte slots; budget YiHi boards give five. Values are retained for >10 years or 1 000 000 write cycles, far beyond normal use. Resistance is read live, so memory only calls the target power; it does not store coil ohms. Some firmware lets you label slots (“40 MTL”, “80 Mesh”) on a 0.96-inch OLED, while others show simple M1–M5. Mechanical-mod purists bypass all electronics, so Memory Mode is strictly for regulated devices.
Usage & Tips
- Set memories after the coil is fully primed and at room temperature for accurate resistance.
- Name each slot on compatible screens to avoid guessing which is which.
- Lock the mod before pocketing; accidental clicks can switch memories and deliver an unpleasant 80 W hit to a 1.2 Ω MTL coil.
- If the device fires but feels weak, check that memory hasn’t reverted—cheap boards sometimes corrupt data when the mAh (milliamp hour)battery drops below 3.2 V. Keep cells above 3.4 V or perform a factory reset and re-save profiles.
- Finally, never rely on memory to override a dry coil; cotton damage happens faster than you can scroll.
History & Context
Evolv’s DNA 20 (2012) introduced rudimentary presets, but the term “Memory Mode” entered mainstream lingo with the DNA 40 (2014) and Smok’s X Cube II (2015). As Australian vapers adopted high-wattage mesh coil tanks and discrete MTL pod mods, multi-slot memory became a must-have, turning sophisticated chipsets into everyday tools rather than hobbyist novelties.
