DigiCards

The DigiMemories (デジメモリ) are items which resemble Memory Sticks and appear in Digimon Xros Wars. The data of "legendary Digimon" are stored on them, and they can be used with the Xros Loader to summon those Digimon. They depict an official Bandai image of a Digimon along with their name, the character for "Technique" (技) written inside a green hexagon, and one of their Special Moves displayed at the bottom. After they have been used they cannot be used in the same zone again, evident by the images becoming pitch black.

Digimon Xros Wars
The Digimon represented by the DigiMemories were a chivalric order that once protected the Digital World but failed to keep it from being torn apart, and as a result were transformed into DigiMemories and scattered throughout the Digital and Real Worlds.

In the Island Zone, while Shoutmon X2 fights against Ebidramon, Whamon informs the group of the existence of another "treasure" besides the Code Crown, the "memories of the legendary heroes", hoping that they will help them. After ChibiKamemon retrieves the case containing five DigiMemories (Agumon, Garurumon, Leviamon, MagnaAngemon and MarineAngemon), Taiki selects Leviamon's DigiMemory and uses its "Rostrum" attack by shouting out "Rostrum, Activate!" (ロストルム発動！), causing one of Ebidramon's pincers to be severed as a result. Next, Neptunmon sends an army of Seadramon, and Taiki uses MarineAngemon's "Ocean Love" to distract them.

In the Magma Zone, Taiki first uses Agumon's DigiMemory of "Triple Baby Flame" to distract AncientVolcamon so that Shoutmon X4 can defeat him. Then later he uses Garurumon's DigiMemory of "Fox Fire" to save Dorulumon from Fused AncientVolcamon.

In the Sand Zone, the DigiMemories are restored to be used again and Taiki uses MagnaAngemon to attack Blastmon's Vilemon and SkullScorpiomon with Gate of Destiny that transports them outside of the ruins. When Xros Heart passed a test to see if they are worthy of having the Zone's Code Crown they are given the Code Crown and four DigiMemories depicting Guilmon, Veemon, Patamon, and Darkdramon.

In the Heaven Zone, Taiki uses Patamon's DigiMemory of "Air Gust" to create a cloud-like staircase for Shoutmon X4 to attack the flying Lucemon Shadowlord Mode.

In the Dust Zone, near the end of the battle against Twilight and Lilithmon, Taiki is given by Puppetmon a new DigiMemory of MetalGarurumon's "Cocytus Breath", which he then uses to beat Lilithmon's fleet of Tankmon.

In the fight against Arkadimon, Persiamon reveals that she had been holding on to the DigiMemories of Gatomon and Impmon, as well as the Veemon and Darkdramon DigiMemories from the Sand Zone, but had forgotten to tell the rest of Xros Heart about them until now. Zenjirou Tsurugi attempts to use the Darkdramon Digimemory to no avail, but when Taiki arrives he succesfully uses the DigiMemory to inflict damage to Arkadimon.

In the Shinobi Zone, Taiki uses the Impmon DigiMemory against Musyamon's forces to create a distraction and attack.

When Taiki, Akari, Zenjirou, and Shoutmon return to the Real World, they find Omnimon's DigiMemory, but when they use it Omnimon appears and explains the DigiMemories to them, and that he was the one who gave Taiki his X Loader and sent him to the Digital World. Soon afterward, Tactimon attacks Tokyo, and Taiki rushes to stop him. During the battle, he reuses the Darkdramon DigiMemory, but it is ineffective. After Zenjirou and Akari's Courage and Friendship allow Shoutmon to digivolve and destroy Tactimon, Omnimon reappears and transports Taiki back to the Digital World.

While fleeing from Dorbickmon in Dragon Land, Taiki uses the Gatomon DigiMemory to help him, Shoutmon, Kiriha, Dracomon, and Lillymon escape from a tunnel rapidly filling with lava.

Digimon Xros Loader
DigiMemory memory sticks, based on the ones that appear in Digimon Xros Wars, can be used to summon "legendary Digimon". They usually come included with models from either the Sofubi Digital Monster Series, which is based on the Digimon of a particular figure, or the Digimon Xros Figure Series, which include DigiMemories that appear in series. Most of the DigiMemories also appear as cards in the Super Digica Taisen series, and are compatible with Digimon X Arena but not the Digimon Xros Loader.

Omnimon
Omnimon is the spiritual remnant of an Omnimon DigiMemory left in the Real World. He is also the one who sends Taiki, Shoutmon, Akari and Zenjirou to the Digital World.

When the humans return to the Real World, Omnimon appears from the DigiMemory. Later, he utilizes the last of his power to send Taiki and Shoutmon back to the Digital World. His DigiMemory is kept by Akari and Zenjirou, hoping one day he can also send them back.
