Low charge consumption memory

A dynamic random access memory is improved by a storage node precharge circuit so as to obtain both high stored voltage level and low charge consumption from a power supply. High voltage levels are written via the precharge circuit. Subsequently, low voltage levels are written via the access transistors and bit lines. As a result, the magnitude of the storage node voltage swing is independent of the magnitude of the bit line voltage swing. A given memory design may therefore be optimized independently for high stored voltage level and low bit line charge consumption.
