System and a method for designing a hybrid memory cell with memristor and complementary metal-oxide semiconductor
View Patent ↗The embodiments herein relates to a hybrid non-volatile memory cell system and architecture for designing integrated circuits. The system comprises CMOS access transistor connected to a memristor which stores a data based on a resistance. The system has a word line for accessing the hybrid memory and two bit lines carrying data of mutually opposite values for transferring a data from the memory. The two terminals of the transistor are connected respectively to a first terminal of the memristor and to a first bit line. The gate terminals of the transistors are coupled together to form a word line. The access transistors control the two bit lines during a read and write operation. A control logic performs a read and write operation with the hybrid memory cells. The memory architecture prevents a power leakage during data storage and controls a drift in a state during a read process.
