Ferroelectric memories which use destructive readout require a rewrite after a read. For such memories every data access adds one cycle of fatigue to the capacitor. High frequency cycling is then required to demonstrate the long term fatigue effects and determine reliability of these memories. To avoid noise and get clean measures of remanent polarization large capacitors are used. Unfortunately, these also present a large capacitive load and attempts to perform high speed cycling are limited by the typically low current drive capabilities of pulse generators. This results in most of the applied voltage being dropped across the output impedance of the driver. In this paper we will describe an exerciser specifically designed to drive multiple ferroelectric capacitors at 6 Mhz. With this system we have measured fatigue characteristics beyond 1013 cycles on 100 × 100 and 20 × 20 μm2 capacitors. |
