  • Patent number: 6353566
    Abstract: A sense amplifier output equalization circuit for a variable operating voltage high density flash memory device is disclosed. The equalization circuit compensates for the varying sensing speeds due to the varying operating voltages by variably adjusting the duration of an equalization pulse which is used to equalize the output stage of the sense amplifier to the input stage.

  • Patent number: 6285627
    Abstract: An equalization circuit for an address transition detector of a high density flash memory device is disclosed. The equalization circuit substantially equalizes the electrical characteristics of a particular signal path to those of another signal path wherein these signal paths transmit trigger signals which further generate other signals. The equalization ensures that resultant signals generated from the trigger signals which traverse these signal paths are generated in the same manner and with the same timing no matter which signal path the trigger signal travels down.
