Kutholwe ukuba sengozini okusha I-DMA (Ukufinyelela Kwememori Okuqondile). Lezi zinhlobo zokuhlaselwa kwe-DMA akuyona into entsha, zaziwa iminyaka, kepha manje iqembu labaphenyi bezokuphepha lithole usongo olusha oluthinta izinhlelo ezinkulu zokusebenza: I-GNU / Linux, i-FreeBSD namanye ama-BSD, iMicrosoft Windows ne-Apple macOS. Ukuhlaselwa okusebenzisa lokhu kuba sengozini kungadlula izindlela zokuvikela ezisunguliwe.
Ngokuxhuma i-plug-hot device enekhompyutha, lokhu kuhlasela kungenziwa. Amadivayisi angahluka kakhulu, kusuka ku-adaptha yenethiwekhi ye-USB, igundane, ikhibhodi, i-pendrive noma i-hard drive yangaphandle, ikhadi lemidwebo langaphandle, amaphrinta, njll. Kepha zithinta ngqo itheku I-Thunderbolt 3okungukuthi, ngakho-ke futhi nase I-USB-C esekelwe phezu kwayo. I-Thunderbolt ivumela ama-peripheral axhunywe ngayo ukuthi adlule izinqubomgomo zokuphepha zesistimu yokusebenza nememori yesistimu, ikwazi ukufinyelela kumadivayisi athile nge-DMA. amakheli enkumbulo (funda bese ubhala) okufanele kugcinwe. Kulezo zindawo zememori, kungaba nemininingwane eyimfihlo njengamaphasiwedi agciniwe, imininingwane yasebhange noma yokungena ngemvume yezinye izinsizakalo ezibalulekile, amanani ayimfihlo agcinwe yisiphequluli, njll.
Futhi i-OS isebenzisa iyunithi IOMMU (I-O unit management management unit) ukuvimba okunye ukuhlaselwa kwe-DMA kwangaphambilini ngokuvimbela amadivayisi asemthethweni wokungena ezindaweni ezithile zememori futhi abavumele kuphela ukuthi bakwazi ukufinyelela kokufanele. Esikhundleni salokho, isitaki esibizwa ngeThunderclap singakhohlisa lokhu kuvikela futhi sikudlule ngezinhloso ezingekho emthethweni.
