ABSTRACT:
In a semiconductor memory in which a large number of memory cells are arrayed in the shape of a matrix, arrangements are provided for a high-sensitivity read-out. In one embodiment, a writing circuit, a voltage amplifier and a sense amplifier are successively connected to a data line that connects input and output ends of the memory cells in an identical row, with the voltage amplifier being formed as a CTD voltage amplifier that is composed of two charge transfer gates and a driving gate located between them. In accordance with another embodiment, a charge supplying circuit and a charge transfer circuit can be coupled between the memory cells and the sense amplifier to allow information transfer without any substantial loss.
