    摘要： A circuit and a method are disclosed for a Schmitt trigger stage which converts transistor-transistor logic (TTL) into metal oxide semiconductor (MOS) logic signal levels using all MOS devices. The circuit reduces the standby current of the n-channel transistor of the input section of the Schmitt trigger stage by adding a MOS diode to the bottom the input section. When higher than normal supply voltages are used, the standby current of the p-channel transistor of the input section can be reduced by adding a MOS diode to the top of the input section. In addition, a small MOS transistor, connected across the output Schmitt trigger inverter, eliminates leakage currents in that inverter.

    摘要： A page mode flash memory or floating gate memory device, including a page buffer based upon low current bit latches, and additional capabilities for parallel read and parallel program verify operations. The present device includes bit latch circuitry and/or method steps that facilitate such parallel operations and avoid data conflicts. Circuitry for separate read signals can serve to isolate the operations. Additionally, circuitry tied to the data verification signal can also be used. A diode type device can be used to isolate signal conditions that might indicate the cell does not need to be programmed. Bit-by-bit precharging of the bit lines can also be employed in order to save precharging power. Additionally, the large capacitance of the dataline might be used to delay discharging a particular dataline, and thereby allow a latch enabling signal to go high, thus eliminating the need for further isolation circuitry, or the like.
