Abstract
A memory system using low impedance memory bitlines that eliminate the need for a precharge clock signal. An equilibration circuit controlled by a reference voltage is connected to the first and second bitlines of a memory cell and is operable to maintain a predetermined equilibrium condition between the first and second bit lines. The equilibration circuit is operable to generate an impedance load in the first and second bit lines at a level that allows generation of differential signals in the bit lines. The memory cell bitlines can move from a sensed state 'low' to the opposite state 'high' without an intervening precharge, thereby providing a significant increase in performance.
