Long-Retention-Time, High-Speed Dram Array With 12-F-2 Twin Cell For Sub 1-V Operation |
Abstract | ||
|---|---|---|
DRAM-cell array with 12-F-2 twin cell was developed and evaluated in terms of speed, retention time, and low-voltage operation. The write and read-out times of the twin-cell array are shorter than those of a single-cell array by 70% and 40% respectively, because of parallel writing and reading of half charge to and from two memory cells. According to measured retention characteristics of the single cells, the twin-cell array improves retention time by 20% compared with the single-cell array at I V and keeps the retention time of the single-cell array at 0.4 V. Furthermore, the cell accepts the plate-driven scheme without the need of a dummy cell, lowering the necessary word-line voltage by 0.4 V. |
