| Abstract(in English) | This papaer discribes two circuit technologies for high density 256Mbit DRAM.The first technology is the Boosted Sense Ground(BSG) sheme in order to improve the characteristic of a data retention. With using this sheme,the sensing time is 1.2ns fater than the conventional sheme.And more the refresh period till the first fail- bit appears becomes 2 times longer than conventional sheme.Next, the second technology is the hierarchical bit-line architecture in order to reduse the number of the sense amplifier.Utilizing this technology,we could realize 256Mbit DRAM with a small chip size 304mm^2. |
