eMMC (Ikarita ya Media Media yashyizwemo)ifata interineti isanzwe ya MMC, kandi ikubiyemo ubwinshi bwa NAND Flash na MMC Mugenzuzi muri chip ya BGA.Ukurikije ibiranga Flash, ibicuruzwa byashyizwemo tekinoroji yo gucunga Flash, harimo kumenya amakosa no gukosora, flash igereranya yohanagura no kwandika, imiyoborere mibi yo gukumira, gukingira amashanyarazi hasi hamwe nubundi buryo bwikoranabuhanga.Abakoresha ntibakeneye guhangayikishwa nimpinduka mubikorwa bya flash wafer nibikorwa imbere mubicuruzwa.Mugihe kimwe, chip imwe ya eMMC ibika umwanya munini imbere yububiko.
Muri make, eMMC = Nand Flash + umugenzuzi + paki isanzwe
Ubwubatsi rusange muri eMMC bwerekanwe kumashusho akurikira:
eMMC ihuza Flash Controller imbere muri yo kugirango irangize imirimo nko gusiba no kwandika kuringaniza, gucunga nabi imiyoborere, hamwe no kugenzura ECC, kwemerera uruhande rwakiriye kwibanda kuri serivisi zo murwego rwo hejuru, bikuraho ibikenewe gutunganywa bidasanzwe bya NAND Flash.
eMMC ifite ibyiza bikurikira:
1. Koroshya igishushanyo mbonera cyibicuruzwa bya terefone igendanwa.
2. Umuvuduko wo kuvugurura urihuta.
3. Kwihutisha iterambere ryibicuruzwa.
eMMC
JEDD-JESD84-A441, yasohotse muri kamena 2011: v4.5 nkuko byasobanuwe muri Embedded MultiMediaCard (e • MMC) Ibicuruzwa v4.5.JEDEC yasohoye kandi JESD84-B45: Ikarita ya Multimedia Ikarita ya e • MMC), igipimo cy’amashanyarazi kuri eMMC v4.5 (verisiyo ya 4.5 ibikoresho) muri Kamena 2011. Muri Gashyantare 2015, JEDEC yasohoye verisiyo 5.1 yubuziranenge bwa eMMC.
Hafi ya terefone igendanwa hagati ya terefone igendanwa ikoresha eMMC5.1 flash yibuka hamwe numuyoboro mugari wa 600M / s.Umuvuduko wo gusoma ukurikirana ni 250M / s, naho umuvuduko wo kwandika ni 125M / s.
Igisekuru gishya cya UFS
UFS: Ububiko rusange bwa Flash, turashobora kubifata nka verisiyo yambere ya eMMC, ikaba ari module yo kubika igizwe na chip yibikoresho byinshi bya flash yibikoresho, kugenzura neza, na cache.UFS ikora inenge eMMC ishyigikira gusa igice-duplex ikora (soma kandi wandike igomba gukorwa ukwayo), kandi irashobora kugera kubikorwa byuzuye-duplex, bityo imikorere irashobora gukuba kabiri.
UFS yagabanijwemo UFS 2.0 na UFS 2.1 mbere, kandi ibipimo byabo byateganijwe byo gusoma no kwandika ni HS-G2 (Umuvuduko mwinshi GEAR2), kandi HS-G3 birashoboka.Ibice bibiri byibipimo birashobora gukora muburyo bwa 1Umuyoboro (umuyoboro umwe) cyangwa 2Lane (dual-umuyoboro).Ni bangahe gusoma no kwandika umuvuduko terefone igendanwa ishobora kugeraho biterwa na UFS flash yibikoresho bisanzwe hamwe numubare wimiyoboro, hamwe nubushobozi bwo gutunganya gukoresha UFS flash yibuka.Inkunga ya bisi.
UFS 3.0 itangiza HS-G4 ibisobanuro, kandi umurongo umwe wumuyoboro wongerewe kugera kuri 11.6Gbps, ibyo bikaba bikubye kabiri imikorere ya HS-G3 (UFS 2.1).Kubera ko UFS ishyigikira imiyoboro ibiri yo gusoma no kwandika, umurongo mugari wa UFS 3.0 urashobora kugera kuri 23.2Gbps, ni 2.9GB / s.Mubyongeyeho, UFS 3.0 ishyigikira ibice byinshi (UFS 2.1 ni 8), itezimbere imikorere yo gukosora amakosa kandi ishyigikira itangazamakuru rya NAND Flash flash.
Kugirango uhuze ibyifuzo bya 5G, UFS 3.1 ifite inshuro 3 umuvuduko wo kwandika wibisekuru byabanjirije rusange-intego yo kubika flash.Disiki ya megabayiti 1,200 ku isegonda (MB / s) yongerera imbaraga imikorere kandi igafasha kwirinda gukabya mugihe ukuramo dosiye, bikagufasha kwishimira umurongo muto wa 5G mwisi ihujwe.
Andika umuvuduko ugera kuri 1.200MB / s (umuvuduko wo kwandika urashobora gutandukana kubushobozi: 128 gigabayite (GB) kugeza kuri 850MB / s, 256GB na 512GB kugeza 1200MB / s).
UFS ikoreshwa kandi muri disiki ikomeye U disiki, 2.5 SATA SSD, Msata SSD nibindi bicuruzwa, UFS isimbuza NAND Flash kugirango ikoreshwe.
