Tsarin sarrafa Nand Flash
Ana sarrafa NAND Flash daga ainihin kayan siliki, kuma ana sarrafa kayan silicon zuwa wafers, waɗanda gabaɗaya an raba su zuwa inci 6, inci 8, da inci 12.Ana samar da wafer guda ɗaya bisa ga wannan duka.Ee, nawa wafer guda nawa za a iya yanke daga wafer an ƙaddara bisa ga girman mutu, girman wafer da yawan amfanin ƙasa.Yawancin lokaci, ana iya yin ɗaruruwan guntun NAND FLASH akan wafer guda ɗaya.
Wafer guda ɗaya kafin marufi ya zama Die, wanda ƙaramin yanki ne da aka yanke daga Wafer ta Laser.Kowane Die guntu ce mai zaman kanta, wacce ta ƙunshi da'irorin transistor marasa adadi, amma ana iya haɗa su azaman naúrar a ƙarshe Ya zama guntu na walƙiya.An fi amfani dashi a cikin filayen lantarki na mabukaci kamar SSD, USB flash drive, katin ƙwaƙwalwar ajiya, da sauransu.
Wafer da ke dauke da wafern NAND Flash, za a fara gwada wafern, bayan an gama gwajin sai a yanke shi a sake gwadawa bayan an yanke, sannan a cire wanda bai mutu ba, ya tsaya tsayin daka, sannan a hada shi.Za a sake yin gwaji don ɗaukar ɓarnar Nand Flash waɗanda ake gani kullun.

Tsarin aikace-aikacen da haɓaka haɓakar NAND Flash
A matsayin matsakaicin ma'auni mai ƙarfi mai ƙarfi-jihar, NAND Flash yana da wasu halaye na zahiri na nata.Tsawon rayuwar NAND Flash bai kai tsawon rayuwar SSD ba.SSDs na iya amfani da hanyoyin fasaha daban-daban don inganta rayuwar SSDs gaba ɗaya.Ta hanyar fasaha daban-daban, za a iya ƙara tsawon rayuwar SSDs da 20% zuwa 2000% idan aka kwatanta da na NAND Flash.
Sabanin haka, rayuwar SSD ba ta daidai da rayuwar NAND Flash ba.Rayuwar NAND Flash galibi ana siffanta shi da zagayowar P/E.SSD ya ƙunshi barbashi na Flash da yawa.Ta hanyar algorithm na diski, ana iya amfani da rayuwar barbashi yadda ya kamata.
Dangane da ka'ida da tsarin masana'antu na NAND Flash, duk manyan masana'antun ƙwaƙwalwar ajiyar filasha suna aiki tuƙuru don haɓaka hanyoyi daban-daban don rage farashin kowane bit na ƙwaƙwalwar walƙiya, kuma suna aiki tuƙuru don ƙara adadin yadudduka na tsaye a cikin 3D NAND Flash.
