Ultra-low power differential structure non-volatile memory compatible with standard cmos process

Abstract

The invention discloses an ultralow power consumption differential structure nonvolatile memory compatible with standard CMOS (Complementary Metal-Oxide-Semiconductor Transistor) process, which aims at solving the problem of the incapability of compatibility with the standard CMOS process. With the adoption of a differential output structure, the area of a storage unit structure is reduced. The ultralow power consumption differential structure nonvolatile memory comprises a plurality of storage units, wherein each storage unit comprises two identical modules; each module comprises a control tube, a tunneling tube, a first reading tube, a second reading unit and five transistors of a selection tube; all the transistors comprise mono-crystal and polycrystal silicon gate structure and gate oxide layers same in thickness; the storage units are compatible with the standard CMOS process. By virtue of the ultralow power consumption differential structure nonvolatile memory compatible with the standard CMOS process, the application cost is reduced; the technique development period is shortened; the ultralow power consumption differential structure nonvolatile memory is good in stability, relatively high in reading speed and high in reliability.
