A WELL-SYNCHRONIZED SENSING EQUALIZING METHOD FOR SUB-1.0-V OPERATINGADVANCED DRAMS

We propose an advanced DRAM array driving technique which can achieve low-voltage operation, which we call a well-synchronized sensing and e qualizing method. This method sets the DRAM array free from the body e ffect, achieves a small influence of the short channel effect, and red uces the leakage current The sense and restore amplifier and equalizer can operate rapidly under a low-voltage operating condition such as 1 .0 V V(CC). Therefore, we can make determining the V(th) easy for the satisfaction of the high-speed, the low-power dissipation, and a simpl e device structure. The well-synchronized sensing and equalizing metho d is applicable to low-voltage operating DRAM's with capacity of 256 M bits and more.
