ABSTRACT:
A high integration dynamic random access memory is provided by this invention. Furthermore, a write method is provided such that the cell size of two-and three-transistor gain cell memories is reduced. A dynamic memory incorporating a thin-channel transistor as the write element such that long data storage retention is achieved in the memory devices of this invention. A dynamic memory cell having low operating power and high density is also realized by this invention.
