  • Grouped plate line drive architecture and method
    Patent number: 6667896
    Abstract: An integrated circuit device includes a two-dimensional array of ferroelectric memory cells in which plate lines within the array are grouped. The grouping of plate lines accommodates the use of larger plate line drivers, such as CMOS driver inverters. Each plate line group may include some but not all of the rows of memory cells and some but not all of the columns of memory cells within the array.
    Type: Grant
