Ƙwaƙwalwar NAND
Faifan yana aiki godiya ga ƙwaƙwalwar NAND: kwakwalwan kwamfuta na semiconductor. Chipsunbin ƙwaƙwalwar wannan ƙwaƙwalwar ajiya sune, da farko, sosai m, kuma na biyu, suna da ƙarfi: idan da farko filashin filashi cikin girma sun ɓace zuwa fayafan gani da suke a wancan lokacin, yanzu ma fayafan Blu-Ray ya wuce ƙarfin. Irin wannan ƙwaƙwalwar, a tsakanin sauran abubuwa, shima ba mai canzawa bane, watau, baya buƙatar tushen wutar lantarki don adana bayanai, sabanin kwakwalwar RAM wanda aka kirkira ta hanyar fasahar.
Koyaya, ƙwaƙwalwar NAND yana da hasara guda ɗaya idan aka kwatanta da sauran nau'ikan na'urorin adanawa. Gaskiyar ita ce rayuwar sabis na waɗannan kwakwalwan kwamfuta yana da iyakance ta wasu keɓaɓɓun hanyoyin haɓakawa (matakai don karanta / rubuta bayani a cikin sel). A matsakaita, adadin karatuttukan-karanta-rubuce shine 30,000 (ya danganta da nau'in guntin ƙwaƙwalwar ajiya). Wannan yana kama da ƙima mai ban mamaki, amma a zahiri yana kusan shekaru 5 na amfani mai yawa. Koyaya, ko da an iyakance iyakar, ana iya ci gaba da amfani da filashin, amma don karanta bayanan. Bugu da kari, saboda yanayin sa, ƙwaƙwalwar NAND yana da matukar rauni ga ɗumbin iko da zubarda wutar lantarki, don haka ku nisantar dashi daga tushen waɗannan haɗarin.
Mai Gudanarwa
Lambar 2 a cikin adadi a farkon labarin ƙaramin microcircuit ne - mai sarrafawa, kayan sadarwa tsakanin ƙwaƙwalwar filasha da na'urorin da aka haɗa (PC, televisions, rediyo mota, da sauransu).
