Kukonza, kugwiritsa ntchito ndi chitukuko cha Nand Flash

Njira yopangira Nand Flash

NAND Flash imakonzedwa kuchokera kuzinthu zoyambilira za silicon, ndipo zinthu za silicon zimasinthidwa kukhala zowotcha, zomwe nthawi zambiri zimagawidwa mainchesi 6, mainchesi 8, ndi mainchesi 12.Chophika chimodzi chimapangidwa potengera mkate wonsewu.Inde, ndi angati opatulira amodzi omwe angadulidwe kuchokera ku mtanda amatsimikiziridwa molingana ndi kukula kwake, kukula kwake ndi kuchuluka kwa zokolola.Nthawi zambiri, mazana a tchipisi ta NAND FLASH amatha kupangidwa pamtanda umodzi.

Chophika chimodzi chisanayambe kulongedza chimakhala Die, chomwe ndi chidutswa chaching'ono chodulidwa kuchokera ku Wafer ndi laser.Die iliyonse ndi chipangizo chodziyimira pawokha, chomwe chimapangidwa ndi mabwalo osawerengeka a transistor, koma amatha kupakidwa ngati unit pamapeto pake Imakhala chip chip.Amagwiritsidwa ntchito kwambiri pazinthu zamagetsi zamagetsi monga SSD, USB flash drive, memory card, etc.

Chophika chomwe chili ndi NAND Flash wafer, chowotchacho chimayesedwa koyamba, ndipo chiyesocho chitatha, chimadulidwa ndikuyesedwanso pambuyo podulidwa, ndipo kufa kosasunthika, kokhazikika, ndi mphamvu zonse kumachotsedwa, kenako kuikidwa.Kuyesedwa kudzachitikanso kuti atseke tinthu tating'ono ta Nand Flash tomwe timawoneka tsiku ndi tsiku.

Zina zonse pamkatewu zimakhala zosakhazikika, zowonongeka pang'ono ndipo motero sizikwanira, kapena zowonongeka.Poganizira za chitsimikizo chaubwino, fakitale yoyambirira idzalengeza kuti kufa kwakufa, komwe kumatanthauzidwa kuti ndi kutaya zinyalala zonse.

Qualified Flash Die original pakeging fakitale idzayika mu eMMC, TSOP, BGA, LGA ndi zinthu zina malinga ndi zosowa, koma palinso zolakwika pakuyika, kapena magwiridwe antchito sali oyenera, tinthu tating'ono ta Flash tisefedwanso, ndipo zinthuzo zidzatsimikiziridwa kupyolera mu kuyesa kolimba.khalidwe.

Opanga ma Flash memory particle amaimiridwa makamaka ndi opanga angapo akuluakulu monga Samsung, SK Hynix, Micron, Kioxia (omwe kale anali Toshiba), Intel, ndi Sandisk.

Pansi pa zomwe zikuchitika pomwe NAND Flash yakunja ikulamulira msika, wopanga ku China wa NAND Flash (YMTC) watulukira mwadzidzidzi kuti atenge malo pamsika.3D NAND yake ya 128-layer 3D NAND idzatumiza zitsanzo za 128-layer 3D NAND kwa woyang'anira zosungirako m'gawo loyamba la 2020. Opanga, omwe akufuna kulowa nawo kupanga mafilimu ndi kupanga misala m'gawo lachitatu, akukonzekera kuti agwiritsidwe ntchito pazinthu zosiyanasiyana zowonongeka monga monga UFS ndi SSD, ndipo zidzatumizidwa ku mafakitale a module nthawi imodzi, kuphatikizapo TLC ndi mankhwala a QLC, kuti awonjezere makasitomala.

Kagwiritsidwe ntchito ndi kakulidwe ka NAND Flash

Monga njira yosungirako yolimba-state drive, NAND Flash ili ndi mawonekedwe akeake.Kutalika kwa moyo wa NAND Flash sikufanana ndi moyo wa SSD.Ma SSD amatha kugwiritsa ntchito njira zosiyanasiyana zamaukadaulo kuti apititse patsogolo moyo wa ma SSD onse.Kupyolera mu njira zosiyanasiyana zamakono, moyo wa SSDs ukhoza kuwonjezeka ndi 20% mpaka 2000% poyerekeza ndi NAND Flash.

Mosiyana ndi izi, moyo wa SSD siwofanana ndi moyo wa NAND Flash.Moyo wa NAND Flash umadziwika makamaka ndi kuzungulira kwa P/E.SSD imapangidwa ndi tinthu tambiri ta Flash.Kupyolera mu disk algorithm, moyo wa particles ukhoza kugwiritsidwa ntchito bwino.

Kutengera mfundo ndi kupanga kwa NAND Flash, onse opanga ma flash memory akugwira ntchito molimbika kupanga njira zosiyanasiyana zochepetsera mtengo pagawo lililonse la kukumbukira kwa flash, ndipo akufufuza mwachangu kuti awonjezere kuchuluka kwa zigawo zoyimirira mu 3D NAND Flash.

Ndi chitukuko chofulumira chaukadaulo wa 3D NAND, ukadaulo wa QLC ukupitilira kukula, ndipo zida za QLC zayamba kuwoneka chimodzi pambuyo pa china.Ndizodziwikiratu kuti QLC ilowa m'malo mwa TLC, monga TLC ilowa m'malo mwa MLC.Komanso, ndi kuwirikiza kawiri kwa 3D NAND single-die capacity, izi zidzayendetsanso ma SSD ogula ku 4TB, ma SSD apamwamba kuti apitirire ku 8TB, ndipo ma QLC SSD adzamaliza ntchito zomwe zasiyidwa ndi TLC SSD ndikusintha pang'onopang'ono ma HDD.zimakhudza msika wa NAND Flash.

Kuchuluka kwa ziwerengero za kafukufuku kumaphatikizapo 8 Gbit, 4Gbit, 2Gbit ndi zina za SLC NAND flash memory zosakwana 16Gbit, ndipo zinthuzo zimagwiritsidwa ntchito pamagetsi ogula, Internet of Things, magalimoto, mafakitale, mauthenga ndi mafakitale ena okhudzana nawo.

Opanga oyambira apadziko lonse lapansi amatsogolera chitukuko chaukadaulo wa 3D NAND.Pamsika wa NAND Flash, opanga asanu ndi mmodzi oyambirira monga Samsung, Kioxia (Toshiba), Micron, SK Hynix, SanDisk ndi Intel akhala akulamulira kwa nthawi yaitali kuposa 99% ya msika wapadziko lonse.

Kuphatikiza apo, mafakitale oyambilira apadziko lonse lapansi akupitiliza kutsogolera kafukufuku ndi chitukuko chaukadaulo wa 3D NAND, ndikupanga zotchinga zaukadaulo.Komabe, kusiyana kwa dongosolo la mapangidwe a fakitale iliyonse yapachiyambi kudzakhala ndi zotsatira zake pa zotsatira zake.Samsung, SK Hynix, Kioxia, ndi SanDisk atulutsa motsatizana zinthu zaposachedwa kwambiri za 100+ 3D NAND.

Pakalipano, kukula kwa msika wa NAND Flash kumayendetsedwa makamaka ndi kufunikira kwa mafoni ndi mapiritsi.Poyerekeza ndi zosungira zakale monga makina osungira, makadi a SD, ma drive olimba ndi zida zina zosungiramo pogwiritsa ntchito NAND Flash tchipisi zilibe makina, palibe phokoso, moyo wautali, kugwiritsa ntchito mphamvu zochepa, kudalirika kwambiri, kukula kochepa, kuwerenga mwachangu komanso kulemba liwiro, ndi kutentha ntchito.Zili ndi mitundu yambiri ndipo ndi njira yachitukuko yosungiramo katundu wamkulu m'tsogolomu.Mkubwela kwa nthawi ya data yayikulu, tchipisi ta NAND Flash tipangidwa bwino mtsogolo.
