Abstract
The present disclosure provides a fusion memory including a plurality of memory cells, wherein each memory cell of the plurality of memory cells includes: a bulk substrate; a source and a drain on the bulk substrate; a channel extending between the source and the drain; a ferroelectric layer on the channel; and a gate on the ferroelectric layer.
Claims12
A fusion memory, comprising:
- a plurality of memory cells, wherein each memory cell of the plurality of memory cells comprises:
- a bulk substrate;
- a source and a drain on the bulk substrate;
- a channel region extending between an area at which the source is located and an area at which the drain is located;
- a ferroelectric layer on the channel region;
- a gate on the ferroelectric layer;
- and
- a gate voltage controller, wherein the gate voltage controller is electrically connected to the gate of the each memory cell and configured to control the gate to operate at a first voltage or a second voltage, an absolute value of the first voltage is less than a reversal voltage at which the ferroelectric layer is polarization reversed, and an absolute value of the second voltage is greater than the reversal voltage at which the ferroelectric layer is polarization reversed.
