ABSTRACT:
A memory has a sense amplifier that provides data onto a global data line that is received by a secondary amplifier. The sense amplifier is precharged to a high voltage and responds to data provided by a selected memory cell on a pair of bit lines. The amplifier is a dynamic amplifier that latches the data but also limits the output voltage swing provided to the secondary amplifier. By limiting the voltage swing on the high-capacitance global data lines, there is significant power savings. The voltage swing that is provided is sufficient for reliable detection by the secondary amplifier.
