Demonstrin selgelt k\u00f5ige lihtsama viisi, kuidas taastada andmeid nutitelefoni NAND-m\u00e4lust, olenemata p\u00f5hjusest, miks see on vajalik. M\u00f5ningatel juhtudel ei t\u00f6\u00f6ta telefon protsessori kahjustuse t\u00f5ttu, emaplaat on vigastatud ja ei ole taastatav, kuid m\u00f5nel juhul on telefon lukus ja andmeid tuleb p\u00e4\u00e4sta.<\/p>\n

\nMul oli au t\u00f6\u00f6tada ettev\u00f5ttes fix-oscomp, OSKOMP-i digitehnika remondi osakonnas. Just siin sain praktiliselt tutvuda selle meetodiga.

\nNAND on t\u00fc\u00fcpi m\u00e4lupulk, mida k\u00f5ige sagedamini kasutatakse kaasaegsetes nutitelefonides.<\/p>\n

NAND struktuur vastavalt Wikipedia-le<\/b>
\n NAND struktuur on kolmem\u00f5\u00f5tmeline maatriks. Aluseks on sama maatriks nagu NOR-is, kuid iga ristumiskohas on \u00fcksikute rakkude j\u00e4rjestikune veerg, mitte \u00fcks transistor. Sellises konstruktsioonis tekib palju l\u00fclituskeeli \u00fches ristumiskohas. Koormuse tihedust saab j\u00e4rsult suurendada (sest igale rakule veerus sobib ainult \u00fcks l\u00fclitusjuht), kuid juurdep\u00e4\u00e4su algoritmidele rakkude lugemisel ja kirjutamisel muutub oluliselt keerulisemaks. Samuti on igas joonis kahte MOS-transistori. Juhttransistor sadestusjoonel (ingl. bit line select transistor), mis on asendatud rakkude veeruga ja sadestusjoonega. Ja juhttransistor maandumise juures, mis asub enne maandust (ingl. ground select transistor).<\/p>\n

\nEmaplaat puhastati, kuid me ei saa protsessorit vahetada, kuna protsessor ja NAND m\u00e4lu on seotud t\u00e4ki kaudu ning me vahetame need samuti paari kaupa. Sellisel juhul v\u00f5tame donorplaadi odavamatelt mudelitelt, antud juhul sobib Xiaomi Redmi Note 5.<\/p>\n
