Abstract
A self timed precharge sense amplifier for allowing high speed reading of a memory cell of a memory array. The self timed precharge sense amplifier uses a precharge device for generating an output voltage which is used to ramp up a voltage level of a column of the memory array where the memory cell is located. State control circuitry is coupled to the precharge device for activating and deactivating the precharge device. A sense amplifier is coupled to the pre- charge device and to the state control circuitry for monitor- ing the output voltage of the precharge device and for signalling the state control circuitry to deactivate the pre- charge device when the output voltage has reached a thresh- old voltage level set by the sense amplifier which is a minimum amount of voltage required to properly read the memory cell.
