Each output node is connected to charge boosting circuitry and to precharge circuitry. The charge boosting circuit receives one or more clock signals. The precharge circuits have a first state allowing the respective pump-stage output node to fluctuate at a level above a standby wordline voltage, and a second state coupling the respective pump-stage output node to the standby wordline voltage.

    摘要: A memory apparatus includes a host device and a slave device. The host device stores verification data. The slave device includes a memory unit, a control unit, and a logic unit. The control unit drives the memory unit to provide storage data in a data transmission sub-period, and further provides a control signal, indicating the first verification data, in a dummy sub-period. The logic unit provides first preamble data, indicating substantially a same data value as the verification data, in the dummy sub-period in response to the first control signal. The preamble data and the storage data are transmitted according to an internal clock signal. The host device samples the first preamble data according to an external clock signal, and determines whether the external and the internal clock signals are synchronized by comparing the first preamble data and the first verification data.

    摘要: Non-volatile memory circuits according to the present invention provide a reference memory having multiple reference cells that is shared among a group of sense amplifiers through an interconnect conductor line. The higher number of reference cells for each reference memory generates a greater amount of electrical current for charging multiple source lines. The multiple source lines are coupled to the interconnect conductor bar for capacitance matching with a source line coupled to a memory cell in a main memory array. After a silicon wafer out, measurements to the capacitance produced by the source line in the main memory array and the capacitance produced by the source line in the reference array are taken for an optional trimming. A further calibration in capacitance matching is achieved by trimming one of the source lines that is coupled to the interconnect conductor bar and the reference memory, either by cutting a portion of the source line or adding a portion to the source line.

    摘要: A reference current is generated by inputting an adjusting current, which is about two or three micro amperes larger than the drain current of the NROM cell having a highest threshold voltage of the flash memory, a reference current with an initial value, effectively the same as the drain current of the NROM cell with a lowest threshold voltage. The method involves sensing the difference between the reference current decreasing from its initial value, and the adjusting current under a predetermined memory speed.
