Abstract:
Semiconductor memory devices and methods of operating the same are provided. The method of operation may include the steps of selecting a ferroelectric memory cell for a read operation, coupling a first pulse signal to interrogate the selected ferroelectric memory cell, the selected ferroelectric memory cell outputting a memory signal to a bit-line in response to the first pulse signal, coupling the memory signal to a first input of a sense amplifier via the bit-line, electrically isolating the sense amplifier from the selected ferroelectric memory cell, and enabling the sense amplifier for sensing after the sense amplifier is electrically isolated from the selected ferroelectric memory cell. Other embodiments are also disclosed.

Claim (Index 16):
A method of operating a ferroelectric memory array, comprising:\n coupling a first plate line to the ferroelectric memory array, wherein the first plate line is associated with a first column, wherein the first plate line is to be coupled to a square pulse signal during a read operation of a selected memory cell; coupling a first word-line to the ferroelectric memory array, wherein the first word-line is associated with a first row of memory cells, wherein the first word-line is to be coupled to a word-line signal; coupling a first bit-line to the ferroelectric memory array, wherein the first bit-line is associated with the first column and electrically connects the selected memory cell to a sense amplifier when the word-line signal is asserted; de-asserting the square pulse signal; de-asserting the word-line signal after the square pulse signal is de-asserted; and subsequent to the word-line signal being de-asserted, coupling an enable signal to the sense amplifier to start a sense operation, wherein the word-line signal remains de-asserted when the enable signal is asserted.
