The Gaia Memories are mysterious USB flash drives imbued with the powers of the Earth itself. Originally created with funding by the Sonozaki Family, these Gaia Memories end up in the possession of Shotaro and Philip, and can only be used through the Double Driver. Compared to the Gaia Memories used by Dopants, the Memories used by Kamen Rider Double are much more refined in appearance, something that Shinkuro Isaka states is indicative of the limits placed on their powers. Two can be inserted into the Double Driver, allowing Shotaro and Philip to transform into Kamen Rider Double. Philip's right-half Gaia Memories called Soul Memories determine the elemental power of Double, while Shotaro's left-half Memories called Body Memories determine the type of attack or weaponry that Double uses.
The Cyclone Memory, also known as the Windy Memory, allows the user to move at fast speeds, controlling the very power of wind, becoming the Windy Warrior. When used, half of Kamen Rider Double becomes the green Cyclonic Right Half. Forms using the Cyclone Memory possess a Windy Stabilizer , a silver scarf hanging from the neck.
Ryu is briefly lent Philip's Cyclone Memory to battle the Weather Dopant. When inserted into the Engine Blade, it allows Kamen Rider Accel to perform a wind-powered Maximum Drive strong enough to wound even the Weather Dopant.
The Joker Memory, also known as the Trump Card Memory, allows the user to increase fighting potential, becoming the Skill Warrior. When used, half of Kamen Rider Double becomes the black Trumping Left Half. When the Joker Memory is placed in the Maximum Slot on the Double Driver, it allows Double to split into two halves to deliver an elemental-powered Maximum Drive attack.
The Heat Memory, also known as the Hot Memory, empowers the user with the element of fire, becoming the Blazing Warrior. When used, half of Kamen Rider Double becomes the red Heated Right Half.
The Metal Memory, also known as the Steel Memory or the Fighter Memory, empowers the user with great strength and magnified resistance to physical harm, becoming the Superpowered Warrior. When used, half of Kamen Rider Double becomes the silver Fighting Left Half. When the Metal Memory is placed in the Maximum Slot on the Metal Shaft, it allows Double to infuse the tips of the Metal Shaft with an elemental-powered Maximum Drive attack.
The Luna Memory, also known as the Illusion Memory, allows the user to cast illusions, stretching limbs and bending gunshots, becoming the Mysterious Warrior. When used, half of Kamen Rider Double becomes the gold Fantastical Right Half.
The Trigger Memory, also known as the Sniper Memory, turns the user into an expert marksman, becoming the Gun Warrior. When used, half of Kamen Rider Double becomes the blue Sniping Left Half. When the Trigger Memory is placed in the Maximum Slot on the Trigger Magnum, it allows Double to fire an elemental-powered Maximum Drive attack.
The Transforming Gaia DinosaurFang Memory, also known as the Fanged Memory, is a special Gaia Memory that was solely created to protect Philip by any means necessary, enabling him and Shotaro to transform into Kamen Rider Double FangJoker. It can change between its Live Mode, which resembles a Dromaeosaurid, and its Memory Mode, the top of which resembles a dinosaur's head. When used, half of Kamen Rider Double becomes the white Fanged Right Half, enabling Double to fight like a berserker while altering the left half to match it in being animalistic in design. Being made to protect Philip, the Fang Memory shows up whenever he is in danger. Unlike the normal transformations into Double, this transformation is initiated by Phillip and the process causes Shotaro to fall comatose and transfer his mind until they revert back to normal.
The Transforming Gaia Bird Xtreme Memory is a special bird-like Gaia Memory that allows Kamen Rider Double to become CycloneJokerXtreme by changing from Live Mode to Memory Mode in order to slide onto the Double Driver. It first appears when Philip is in mortal danger from being attacked by the Weather Dopant, and it digitizes him where Shroud confronts him about his mission to save the Earth. The Xtreme Memory's powers come directly from the true Gaia Memory and are accessed through the Crystal Server on CycloneJokerXtreme. To initiate its Maximum Drive, the Double Xtreme Rider Kick, the Xtreme Memory is closed and then re-opened. A variation of the Double Xtreme, the Double Prism Xtreme, is where Double inserts the Prism Memory in the Maximum Slot of the Double Driver before closing and re-opening the Xtreme Memory. When Philip dissolves after his final battle as Double, the Xtreme Memory which holds the data of his mind and body does as well. However, after Wakana sacrifices her life, she brings back the Xtreme Memory which holds Philip's body until his physical form is restored.
The Prism Memory is the Gaia Memory for the Prism Bicker sword and shield. It serves as a storage for other Gaia Memory powers and links the power of four Maximum Drives into one. When placed in the Maximum Slot of the Double Driver, it allows Double CycloneJokerXtreme to execute the Double Prism Xtreme Maximum Drive.
The Accel Memory, or Acceleration Memory, is Kamen Rider Accel's primary Gaia Memory. This enables Ryu to transform into Kamen Rider Accel and access his primary Maximum Drive, as well as allow him to assume Bike Form.
The Engine Memory is a Gaia Memory that gives the Engine Blade its various different powers. It is not a true Gaia Memory however, and its powers are linked to those of the Accel Memory. This allows it to have more than one ability, each based on a different type of engine: Steam, which creates a wave or wall of hot steam; Jet , which allows the Engine Blade to execute super heated slashes or fire a bladed energy wave; and Electric, which allows the Engine Blade to perform electrically charged slashes or fire a bolt of electricity.

Eternal uses the T2 Eternal Memory to transform. Eternal can use other T2 Gaia Memories to access their powers like the T2 Unicorn Memory to create an energy drill around his fist and the T2 Zone Memory to summon the other T2 Gaia Memories to him.
The Skull Memory, also called the Skeleton Memory, is Kamen Rider Skull's only memory, enabling his transformation as well as powering his Skull Magnum gun.
