Claim 12:
13. An image sensor unit, comprising:
a pixel unit, comprising a photodiode, a transmission transistor, and a reset transistor; the photodiode configured to convert received optical signal into an analog electrical signal, a source of the transmission transistor connected to the photodiode, and both a drain of the transmission transistor and a source of the reset transistor are connected to a floating diffusion area; and
a resistive random access memory unit (RRAM unit) connected to the pixel unit, the RRAM unit comprising at least one resistive random access memory (RRAM) configured to convert the analog electrical signal into a resistance value and a logic circuit configured to control reading and writing of the at least one RRAM, an input terminal of the logic circuit connected to the floating diffusion area, and an output terminal of the logic circuit connected to an upper electrode of the RRAM, and a lower electrode of the RRAM connected to a variable external voltage.
