A cewar majiyoyin masana'antu a Taiwan, wanda Albarkatun Intanet DigiTimes, masana'antar ƙwaƙwalwar ajiya ta China ChangXin Memory Technologies (CXMT) tana kan shirya layukan ƙirƙira don yawan adadin ƙwaƙwalwar LPDDR4. ChangXin, wanda kuma aka sani da Innotron Memory, an ce ya kirkiro nasa tsarin samar da DRAM ta hanyar amfani da fasahar 19nm.
Don samar da ƙwaƙwalwar ajiyar kasuwanci a farkon kasuwancin mm 300, ChangXin ya zama dole a farkon rabin shekarar 2019. Kash, wannan bai faru ba tukuna. Amma farkon samar da kwakwalwan kwamfuta na 8-Gbit DDR4 LPDDR4 zai kasance tare da haɓaka iya aiki zuwa 20 dubu 300-nm silicon wafers kowane wata. Matsakaicin ƙarfin layin a cikin kasuwancin ChangXin ya kai 125 dubu 300 wafers kowace wata. Amma wannan ma ba iyaka ba ne. Kamfanin ya ce a shekara mai zuwa zai fara gina masana'anta na biyu don sarrafa ma'adinan ƙwaƙwalwar ajiya 300mm.
A sa'i daya kuma, wannan masana'anta na kasar Sin na iya fuskantar matsaloli daban-daban. Bari mu tuna cewa kamfani na farko na kasar Sin da zai fara samar da ƙwaƙwalwar DRAM mai yawa shine Fujian Jinhua. Amurka tare da hana siyan kayan aikin samarwa daga abokan Amurka. A Taiwan, sun yi imanin cewa ChangXin zai fuskanci matsaloli iri daya da Fujian. Bugu da ƙari, ta ɗauki ƙwararrun injiniyoyi daga tsohon reshen Taiwan na Elpida na Japan, wanda American Micron ya mamaye kasuwancinsa. Masu sharhi suna tsammanin da'awar a kan ChangXin daga Micron da takunkumi idan bangaren China bai amsa ba.
A cikin layi daya, ChangXin yana haɓaka tsarin fasaha don samar da ƙwaƙwalwar ajiya tare da matakan 17 nm. Ana sa ran kammala ci gaba a cikin 2021. Wataƙila, shukar ChangXin ta biyu za ta fara aiki tare da samar da lu'ulu'u na DRAM tare da waɗannan ka'idoji. Sai dai idan, ba shakka, takunkumin Amurka da makirce-makircen Micron sun zama cikas da ba za a iya warwarewa a hanyarta ba.
