Abstract
Description
Claims (1)
- SRAM 메모리 셀에 있어서,전원전압(Vdd)과 부하 소자 사이에 한 쌍의 멤리스터(memristor)소자를 추가하여 SRAM 메모리 셀에 공급되는 상기 전원전압(Vdd)이 차단되면 SRAM 메모리 셀의 래치회로에 존재하는 데이터를 읽어들어 상기 멤리스터 소자에 저장하고, 상기 전원전압(Vdd)의 공급이 재개되면 상기 한 쌍의 멤리스터 소자 내부의 저항차에 의하여 상기 SRAM 메모리 셀의 래치회로에 저장되었던 값을 복원시키도록 동작하는 것을 특징으로 하는 멤리스터 소자를 적용한 비휘발성 정적 랜덤 액세스 메모리 셀.
