Ho theha le nts'etsopele ea lisebelisoa bakeng sa polokelo e sa fetoheng ea data ea dijithale e 'nile ea tsoela pele ka lilemo tse mashome. Katleho ea 'nete e entsoe lilemo tse ka tlase ho tse 20 tse fetileng ke mohopolo oa NAND, leha nts'etsopele ea eona e qalile lilemo tse 20 pejana. Kajeno, hoo e ka bang halofo ea lekholo la lilemo ka mor'a ho qala lipatlisiso tse kholo, ho qaleha ha tlhahiso le boiteko bo sa khaotseng ba ho ntlafatsa NAND, mofuta ona oa mohopolo o haufi le ho qeta matla a eona a tsoelo-pele. Hoa hlokahala ho rala motheo oa phetoho ho sele e 'ngoe ea memori e nang le matla a molemo, lebelo le litšobotsi tse ling. Ka nako e telele, mohopolo o joalo e ka ba mofuta o mocha oa memori ea ferroelectric.
Ferroelectrics (lentsoe ferroelectrics le sebelisoa libukeng tsa kantle ho naha) ke li-dielectrics tse nang le mohopolo oa lebala la motlakase le sebelisitsoeng kapa, ka mantsoe a mang, li khetholloa ke polarization e setseng ea litefiso.

Lilemong tse tharo tse fetileng, bo-rasaense ba MIPT theknoloji ea ho etsa thepa ea filimi e tšesaane bakeng sa memori ea ferroelectric e thehiloeng ho hafnium oxide (HfO2). Hape sena ha se thepa e ikhethang. Dielectric ena e 'nile ea sebelisoa ka lilemo tse' maloa ka tatellano ho etsa li-transistors tse nang le liheke tsa tšepe ho li-processor le lintlha tse ling tsa digital. Ho ipapisitsoe le lifilimi tsa alloy polycrystalline tsa hafnium le zirconium oxides tse nang le botenya ba 2,5 nm tse hlahisitsoeng ho MIPT, ho ne ho ka khoneha ho theha liphetoho ka thepa ea ferroelectric.
E le hore li-capacitor tsa ferroelectric (joalokaha li qalile ho bitsoa MIPT) li sebelisoe e le lisele tsa mohopolo, ho hlokahala hore ho finyelloe polarization e phahameng ka ho fetisisa, e hlokang thuto e qaqileng ea mekhoa ea 'mele ho nanolayer. Haholo-holo, fumana mohopolo oa kabo ea matla a motlakase ka har'a lera ha motlakase o sebelisoa.
