An adaptive reference generation scheme for 1T1C FeRAMs
A reference time, instead of a reference voltage, is generated used to compare stored "0" and "1" in a race of bitlines towards reaching a threshold voltage in a 1T1C FeRAM. The reference time is adaptive, tracking process variations, aging, and fatigue of ferroelectric capacitors. This scheme is implemented in a 256/spl times/128-bit testchip in a 0.35 /spl mu/m ferroelectric process and achieves a 40 ns access time at 3 V.
