Ferroelectric memory

摘要

A nonvolatile memory cell in the form of an SRAM is composed of ferroelectric capacitors and transistors for amplification. The memory cell comprises a first capacitor (FC1) connected between a first terminal (ND1) and a common terminal (CP). A second capacitor (FC2) is connected between a second terminal (ND2) and the common terminal. A first transistor (N1) has a current path connected between the first terminal and a reference terminal (GND) and has a control terminal connected to the second terminal. A second transistor (N2) has a current path connected between the second terminal and the reference terminal and has a control terminal connected to the first terminal.
