Flash nco yog ib daim ntawv ntawm semi-dhau technology thiab hluav taws xob reprogrammable nco. Tib lub tswvyim tuaj yeem siv hluav taws xob hauv tshuab hluav taws xob los ntsuas cov teeb meem ua kom tiav thev naus laus zis. Hauv lub neej txhua hnub, lub tswvyim no tau tsau rau ntau yam ntawm cov khoom siv khov kho uas tau khaws cia cov ntaub ntawv.

Cov Lus Qhia

Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov thev naus laus zis no yog raws li cov kev hloov pauv thiab cov ntawv sau npe hauv cov chaw sib cais ntawm cov nqi hluav taws xob hauv cov qauv hluav taws xob. Qhov kev hloov ntawm tus nqi no, uas yog, nws cov ntaubntawv povthawj siv thiab cov lwv, tshwm sim nrog kev pabcuam ntawm daim ntawv thov nyob nruab nrab ntawm qhov chaw thiab lub rooj vag ntawm nws lub peev xwm ntau dua. Yog li, qhov hluav taws xob kom muaj zog txaus yog tsim nyob nruab nrab ntawm cov transistor thiab hnab tshos hauv daim teb dielectric nyias. Qhov no yog li cas cov qhov cuam tshuam tshwm sim.

Cov khoom siv nco tau raws li kev hloov pauv tus nqi. Nws qee zaum cuam tshuam nrog kev txuam cov txiaj ntsig ntawm kev tsis tuaj yeem hloov pauv hauv nws cov qauv. Yog li no, cov naj npawb ntawm kev nkag yog txwv rau lub eeb cell. Daim duab no rau MLC feem ntau yog 10 txhiab units, thiab rau SLC - txog 100 txhiab units.

Cov ntaub ntawv khaws cia sijhawm yog txiav txim siab los ntawm lub sijhawm khaws cov nqi, uas feem ntau tau hais los ntawm feem ntau cov khoom lag luam hauv tsev. Nws tsis pub dhau kaum txog nees nkaum xyoo. Txawm hais tias cov tuam ntxhab tsuas yog muab kev lav rau thawj tsib xyoos. Nws yuav tsum raug sau tseg, txawm li cas los xij, tias MLC cov khoom muaj cov ntaub ntawv khaws cia luv dua li SLC cov khoom siv.

Tus qauv hierarchical ntawm lub cim xeeb flash tau piav qhia los ntawm qhov tseeb hauv qab no. Cov txheej txheem xws li sau ntawv thiab lwv, nrog rau nyeem cov ntaub ntawv los ntawm lub flash drive, tshwm sim nyob rau hauv cov loj loj ntawm ntau qhov sib txawv. Piv txwv li, ib qho thaiv lwv yog loj dua qhov sau thaiv, uas nyob rau hauv lem yog me dua qhov nyeem thaiv. Qhov no yog qhov sib txawv ntawm qhov cim xeeb flash ntawm qhov ib qho. Raws li qhov tshwm sim, txhua yam ntawm nws lub microcircuits muaj cov qauv hais tawm theem siab. Lub cim xeeb yog li no muab faib ua cov blocks, thiab cov ntawd rau hauv cov nplais thiab nplooj ntawv.

Kev ceev ntawm kev lwv, nyeem ntawv thiab sau ntawv yog qhov sib txawv. Piv txwv li, qhov lwv sai yuav txawv ntawm ib mus txog pua pua ntawm milliseconds. Nws nyob ntawm qhov loj me ntawm cov ntaub ntawv tau raug lwv. Cov ntaubntawv povthawj siv ceev yog kaum lossis ntau pua microseconds. Txoj kev nyeem ntawv nrawm feem ntau yog kaum tawm ntawm nanoseconds.

Cov yam ntxwv ntawm kev siv cim xeeb flash yog dictated los ntawm nws cov nta. Nws raug tso cai los tsim thiab muag microcircuits nrog qee cov lej ntawm lub cim xeeb tsis zoo. Kom qhov feem pua no tsawg dua, txhua nplooj ntawv tau muab nrog me me ntxiv ua ke.

Qhov tsis muaj zog ntawm lub cim xeeb flash yog tias tus lej ntawm kev rov ua dua tshiab ntawm ib nplooj ntawv yog txwv. Qhov xwm txheej dhau los zuj zus vim qhov tseeb hais tias cov ntaub ntawv xa tawm feem ntau sau rau tib qhov chaw cim xeeb.
