摘要： A pre-amplifier portion of a sense amplifier for a dual bank architecture simultaneous operation flash memory device is provided. The sense pre-amplifier circuit includes two inverting amplifiers, the second inverting amplifier providing a feedback loop for the first inverting amplifier. In addition, special “kicker” circuitry raises the sense pre-amplifier's input signal line to its operating level. The combination of inverting amplifiers, feedback loop and level raising circuitry is configured to provide higher bandwidths for the sense pre-amplifier to accommodate low capacitive loading resulting from a small memory bank. The combination is also configured to provide faster raising of the input signal line to operating level to accommodate high capacitive loading resulting from a large memory bank. The combination is also configured to provide increased signal margins at the output of the sense pre-amplifier.

摘要： An address transition signal generator for a dual bank flash memory device is disclosed. The generator includes signal transition detectors which monitor control signals of the device for transitions in their logical values. Upon detection of a signal transition, the transition detectors send a signal across equidistant signal paths to bank address transition detect signal generator circuits. This results in simultaneous generation of the address transition detect signal from each of the bank address transition detect signal generator circuits.

摘要： A flash memory chip including a synchronization circuit for multiplexed sense amplifier output signal paths is disclosed. The synchronization circuit includes a signal generator, sense amplifiers and an output multiplexer. The arrival of data from the sense amplifiers to the output multiplexer is equalized. Equalization is achieved by adjusting the signal path length, and thereby the resistance and capacitance, of the signal paths from the signal generator to the sense amplifiers which carry the signal to cause the sense amplifiers to transmit their data to the output multiplexers.

摘要： A memory device is disclosed that is operable with a supply voltage (Vcc) within an electronic system. The memory device is selected or placed in a standby mode by electric signals from the electronic system. The memory device includes an external voltage buffer circuit for buffering the electric signals that are generated by the electronic system using an external supply voltage. The external voltage buffer circuit includes a clamping circuit and an activation circuit. The clamping circuit generates a clamped signal with the external supply voltage and the supply voltage (Vcc). The activation circuit is responsive to the clamped signal and the electric signals and generates an output signal with the supply voltage (Vcc). The external voltage buffer circuit maintains low standby current during the standby mode since it operates with both the supply voltage (Vcc) and the external supply voltage.
