摘要： A nonvolatile random access memory cell (10) includes a static random access memory circuit and a corresponding nonvolatile memory circuit. The volatile memory circuit operates in a conventional manner and has first and second data states. Upon receipt of a store command signal a charge storage node is driven to either a first or a second charge state, depending upon the data state in the volatile memory circuit. For one charge state the charge storage signal is gated through a transistor (64) and a capacitor (68) to a floating gate node (44). Charge is transferred to and from the floating gate node (44) through current tunneling elements (48,50) which comprise a dielectric fabricated on a monocrystalline substrate. For the recall operation a recall command signal is applied to a transistor (52) which couples a transistor (42) to the DATA node (22) of the volatile memory circuit. If a positive charge state has been stored at the charge storage node (44) the transistor (42) is rendered conductive to pull the DATA node (22) to ground to restore the data state to the volatile memory circuit. If a negative charge state has been stored at the charge storage node (44) there is no load applied to either the DATA node (20) or the DATA node (22). The cross-couple transistors, (12,14) are fabricated to have different lengths such that the node (22) is driven to a high voltage state whenever a default condition is encountered, thereby restoring the original data state to the volatile memory circuit.

摘要： A nonvolatile memory subsystem includes DRAMs and a battery-backed controller chip. The controller chip monitors the system power supply level to ascertain power fault conditions. When a power fault is detected, the controller provides the DRAMs with both a regulated supply voltage and appropriately timed refresh signals.After the system power supply has returned to specification, the controller continues to generate refresh control signals until the commands it to stop.

摘要： An oscillator with reduced temperature-dependence. A time-delay circuit uses both a pull-up resistor and a pull-down resistor, of two different types, to charge a capacitor. The material with the smallest available thermal coefficient of resistance (TCR) is used for the pull-up resistor. Another material, with a larger positive TCR, is used for the pull-down resistor. The oscillator preferably includes two separate time-delay circuits, so that the frequency of the oscillator is dependent on the charging delay of each of the time-delay circuits, but is independent of discharging delay.

摘要： A dynamic load circuit (34) selectively applies a high voltage state to a circuit node (42). A clock signal is coupled to a first node (54) and the inverse of the clock signal is coupled to a second node (60). Isolation transistors (50, 70) are controlled by the voltage level at the circuit node (42) to isolate the clock signals from the first and second nodes (54, 60) when the circuit node (42) is at a low voltage state. A high voltage signal V.sub.pp is coupled through a transistor (58) to the first node (54). The voltage at the first node (54) is coupled through a transistor (56) to the circuit node (42). The circuit node (42) is further coupled through transistors (62, 64) to the second node (60). The application of the alternating positive transistions of the clock and inverse clock signal cause the circuit (34) to apply a progressively increasing voltage to the circuit node (42). The dynamic load circuit (34) functions even if the threshold voltages of the high voltage transistors therein are almost as high as the supply voltage.

摘要： A battery charger with charging parameter values derived from communication with a battery pack to be charged. Communication is over a one-wire bus with battery pack transmissions in response to charger inquiries. The battery charger may be in the form an integrated circuit driving a power transistor or other controllable DC supply. A battery pack may contain a program with multiple charging currents and charging interval termination methods such as time, temperature rise, and incremental voltage polarity. A lack of communication may be invoke a default charging program or denial of access to the charger. The charger also communicates over a high-speed three-wire bus with an external computer for analysis of identification information acquired from the battery and for control of the charger.
