    摘要: The invention relates to a method and a circuit for regulating a pulse synchronization signal (ATD) for the memory cell read phase in semiconductor integrated electronic memory devices. The pulse signal (ATD) is generated upon detection of a change in logic state of at least one of a plurality of address input terminals of the memory cells, so as to also generate an equalization signal (SAEQ) to a sense amplifier. The SAEQ pulse is blocked (STOP) upon the row voltage reaching a predetermined sufficient value to provide reliable reading. Advantageously, the pulse blocking is produced by a logic signal (STOP) activated upon a predetermined voltage value being exceeded during the overboost phase of the addressed memory row.

    摘要: An integrated device having an N-type well region formed in a P-type substrate and an N.sup.+ type contact ring housed in the well region. The well region forms respective capacitors with a conductive layer superimposed on the substrate, and with the substrate itself. The conductive layer and the substrate are grounded, and the contact ring is connected to the supply, so that the two capacitors are in parallel to each other and, together with the internal resistance of the well region, form a filter for stabilizing the supply voltage. When connected to an input buffer stage of the device, the filter provides for damping the peaks produced on the supply line of the input buffer by high-current switching of the output buffers.

    摘要: An address transition detection circuit having a number of cells supplied with respective address signals and outputs connected in a wired NOR configuration to generate a pulse signal on detecting transitions of their respective address signals. The pulse signal is supplied to a source stage for generating an address transition signal having a first and second switching edge on receiving the pulse signal. The source stage has a monostable stage for generating an end-of-transition signal with a predetermined delay following reception of the pulse signal; and an output stage connected to the cells and to the monostable stage, which generates the first switching edge of the address transition signal on receiving the pulse signal, and the second switching edge on receiving the end-of-transition signal. The monostable stage presents a compensating structure for maintaining the delay in the switching of the end-of-transition signal despite variations in temperature and supply voltage.

    摘要: A temperature-related voltage generating circuit has an input terminal receiving a control voltage independent of temperature, and an output terminal delivering a temperature-related control voltage. The input and output terminals are connected together through at least an amplifier stage adapted to set an output reference voltage from a comparison of input voltages. The voltage generating circuit also includes a generator element generating a varying voltage with temperature and connected between a ground voltage reference and a non-inverting input terminal of the amplifier stage. The amplifier stage has an output terminal adapted to deliver a multiple of the varying voltage with temperature to an inverting input terminal of a comparator stage. The comparator stage has its output connected to the temperature-related voltage generating circuit and a non-inverting input terminal receiving the control voltage independent of temperature to evaluate the difference between the control voltage independent of temperature and said voltage being a multiple of the varying voltage with temperature and to output a temperature-related control voltage having at room temperature a mean value which is independent of its thermal differential and increases with temperature. The voltage generating circuit can be incorporated into a regulator for a drain voltage of a single-supply memory cell.

    摘要: A band-gap reference voltage generator comprises an operational amplifier comprising a first input and a second input, the first input being coupled to a first feedback network and the second input being coupled to a second feedback network both coupled to an output of the operational amplifier providing a reference voltage. The first feedback network contains an emitter-base junction of first bipolar junction transistor and the second feedback network contains an emitter-base junction of second bipolar junction transistor. A selectively activated current supply supplies a bias current to the operational amplifier, the current supply being deactivatable in a substantially zero power consumption operating condition for turning the reference voltage generator off. A start-up circuit activated upon start-up of the reference voltage generator for a fixed, prescribed time interval forces a start-up current to flow through the first bipolar junction transistor means.
