Abstract

En selvinnstillende ikke-volatil mirmecelle (200) som omfatter et lite sideveggs- mellomsjikt (239) som er elektrisk koblet og plassert ved siden av et hovedflytende portelekttode-område (212) avdekkes. Både det lille sideveggs-mellomsjiktet og hoved- flytende portelekttode-området formes på et substtat (204) og begge former den flytende portelekttoden til den ikke-volatile mirmecellen. Begge isoleres elektrisk fra substtatet av et oksidsjikt (208, 232, 242) som er tynnere (260, 232,242) mellom det lille sideveggs-mellomsjiktet og substtatet; og tykkere (263, 208) mellom hovedflytende portelekttode-området og substtatet. Det lille sideveggs-mellomsjiktet kan lages lite; og derfor kan også det tyrme oksid-sjikt-arealet lages lite for å skape en liten bane som elekttoner kan turmelere gjermom og irm i den flytende portelekttoden.
