Abstract:
Methods and apparatuses for erasing data on a plurality of ferroelectric memory cells in a memory cell array in a memory apparatus are disclosed. An example apparatus includes: a memory cell array including a first plurality of word lines; a digit line; and a plurality of ferroelectric memory cells; a control circuit that provides a section select signal and a word line select signal to select a second plurality of word lines among the first plurality of word lines responsive to an address; and an address decoder that activates the second plurality of word lines. Each ferroelectric memory cell includes: a ferroelectric capacitor having a first terminal coupled to a cell plate node and a second terminal coupled to a selection circuit that couples the digit line to the second terminal responsive to a signal on a corresponding word line of the second plurality of word lines.
