ABSTRACT:
A power down scheme for a regulated sense amplifier power in DRAM. The power-supply level voltage Vccsa of a sense amplifier is turned on only within a certain time duration, which has no relationship with the word line turn-on time. The power down scheme includes control logic gates and time delay circuits which can be triggered by two internal control signals from other control modules in order to generate a power-down control signal for the bit line sense amplifier.
