Kodi ECC RAM ndi chiyani ndipo imagwira ntchito bwanji?

M'dziko lamakono lamakono, kukhulupirika kwa deta ndi kudalirika ndizofunikira kwambiri.Kaya ndi seva, malo ogwirira ntchito kapena makompyuta ochita bwino kwambiri, kuwonetsetsa kulondola komanso kusasinthika kwazomwe zasungidwa ndikofunikira.Apa ndipamene Error Correcting Code (ECC) RAM imayamba kuseweredwa.ECC RAM ndi mtundu wakukumbukira komwe kumapereka kukhulupirika kwa data komanso chitetezo ku zolakwika zofalitsa.

Kodi ECC RAM ndi chiyani kwenikweni?Zikuyenda bwanjik?

ECC RAM, yachidule ya Error Correcting Code RAM, ndi gawo lokumbukira lomwe lili ndi zozungulira zowonjezera kuti muwone ndikuwongolera zolakwika zomwe zingachitike pakutumiza ndikusunga.Ndizofalaamagwiritsidwa ntchito m'mapulogalamu ovuta kwambiri monga ma seva, makompyuta a sayansi, ndi mabungwe azachuma, kumene ngakhale zolakwika zazing'ono zimatha kukhala ndi zotsatira zoopsa.

Kuti mumvetse mmeneECC RAM imagwira ntchito, tiyeni timvetsetse mwachidule zoyambira zamakompyuta.Memory yofikira mwachisawawa (RAM) ndi mtundu wa kukumbukira kosakhazikika komwe kumasunga kwakanthawi pomwe kompyuta ikugwiritsa ntchito.CPU (Central Processing Unit) ikafunika kuwerenga kapena kulemba zambiri, imapeza zomwe zasungidwa mu RAM.

Ma module a RAM achikhalidwe(otchedwa non-ECC kapena RAM ochiritsira) gwiritsani ntchito pang'ono pa selo imodzi ya kukumbukira kusunga ndi kusamutsa deta.Komabe, mayunitsi osungirawa amatha kulakwitsa mwangozi zomwe zingayambitse kuwonongeka kwa data kapena kuwonongeka kwadongosolo.ECC RAM, kumbali ina, imawonjezera mulingo wowonjezera wowongolera zolakwika pagawo la kukumbukira.

ECC RAM imathandizira kuzindikira ndi kukonza zolakwika pogwiritsa ntchito zida zowonjezera zokumbukira kuti zisunge zofananira kapena zowunikira zolakwika.Zowonjezera izi zimawerengedwa kutengera zomwe zasungidwa mu cell cell ndipo zimagwiritsidwa ntchito kutsimikizira kukhulupirika kwa chidziwitso pakuwerenga ndi kulemba ope.chakudya.Ngati cholakwika chizindikirika, ECC RAM imatha kukonza zolakwikazo momveka bwino, ndikuwonetsetsa kuti zomwe zasungidwa zimakhala zolondola komanso zosasinthika.Izi zimasiyanitsa ECC RAM ndi RAM yokhazikika chifukwa imapereka chitetezo chowonjezera ku zolakwika za kukumbukira.

Chiwembu chomwe chimagwiritsidwa ntchito kwambiri ndi ECC ndi kukonza zolakwika kumodzi, kuzindikira zolakwika ziwiri (SEC-DED).Muchiwembu ichi, ECC RAM imatha kuzindikira ndikuwongolera zolakwika zamtundu umodzi zomwe zitha kuchitika m'maselo okumbukira.Kuphatikiza apo, imatha kuzindikira ngati cholakwika chapawiri chachitika, koma sichingakonze.Ngati cholakwika chapawiri chizindikirika, dongosololi limatulutsa uthenga wolakwikad imachitapo kanthu moyenera, monga kuyambiranso dongosolo kapena kusintha makina osunga zobwezeretsera.

Chimodzi mwazinthu zazikulu za ECC RAM ndi chowongolera kukumbukira, chomwe chimagwira ntchito yofunika kwambiri pakuzindikira zolakwika ndi kukonza.Woyang'anira kukumbukira ali ndi udindo wowerengera ndi kusunga chidziwitso cha paritykufotokozera pa nthawi yolemba ndi kutsimikizira mfundo zofananira panthawi yomwe mukuwerenga.Ngati cholakwika chazindikirika, woyang'anira kukumbukira atha kugwiritsa ntchito masamu masamu kuti adziwe zomwe zimayenera kuwongoleredwa ndikubwezeretsa zolondola.

Ndizofunikira kudziwa kuti ECC RAM imafuna ma module okumbukira komanso bolodi lomwe limathandizira magwiridwe antchito a ECC.Ngati chilichonse mwazinthu izi chikusowa, RAM yopanda ECC imathakugwiritsidwa ntchito m'malo mwake, koma popanda phindu lowonjezera la kuzindikira ndi kukonza zolakwika.

Ngakhale ECC RAM imapereka mphamvu zowongolera zolakwika, ilinso ndi zovuta zina.Choyamba, ECC RAM ndiyokwera mtengo pang'ono kuposa yanthawi zonse yopanda ECC RAM.Zowonjezera zozungulira ndi kuwongolera zolakwika kumabweretsa ndalama zambiri zopangira.Chachiwiri, ECC RAM imabweretsa chilango chochepa chifukwa cha kuwerengera zolakwika.Ngakhale kukhudzidwa kwa magwiridwe antchito nthawi zambiri kumakhala kochepa ndipo nthawi zambiri kumakhala kocheperako, ndikofunikira kulingalira za mapulogalamu omwe kuthamanga ndikofunikira.

ECC RAM ndi mtundu wapadera wa kukumbukira womwe umapereka kukhulupirika kwa data komanso chitetezo ku zolakwika zofalitsa.Pogwiritsa ntchito zida zowonjezera zowunikira zolakwika ndi ma aligorivimu apamwamba, ECC RAM imatha kuzindikira ndikuwongolera zolakwika, kuwonetsetsa kuti zidziwitso zosungidwa ndizolondola komanso zodalirika.Ngakhale ECC RAM ingakhale yokwera mtengo pang'ono ndikukhala ndi zotsatira zochepa, ndizofunika kwambiri pazinthu zovuta zomwe kukhulupirika kwa deta kuli kofunika kwambiri.
