Abstract:
Devices and methods for sensing a memory cell are described. The memory cell may include a ferroelectric memory cell. During a read operation, a cascode may couple a precharged capacitor with the memory cell to transfer a charge between the precharged capacitor and the memory cell. The cascode may isolate the capacitor from the memory cell based on the charge transferred between the capacitor and the memory cell. A second capacitor (e.g., a parasitic capacitor) may continue to provide an additional amount of charge to the memory cell during the read operation. Such a change in capacitance value during the read operation may provide a large sense window due to a non-linear voltage characteristics associated with the change in capacitance value.

Claim (Index 1):
A device, comprising:\n a memory cell configured to store a logic state; a capacitor configured to integrate a charge associated with the memory cell during a read operation; a sense component configured to determine the logic state stored on the memory cell during the read operation; a first cascode coupled with the memory cell and a first node; a second cascode coupled with the capacitor and the first node; and a transistor coupled with the first node and the sense component and configured to selectively couple the first node with the sense component during the read operation after the capacitor is isolated from the first node.
