摘要： Improved transistor array device performance is obtained by use of bias voltage regulation which tracks with a fraction of a monitor transistor threshold voltage. The circuitry and methods are especially useful for improving the performance of transistor array devices such as DRAM and embedded DRAM. These benefits are obtained especially when at least two bias voltages normally supplied to the array are regulated by tracking with a fraction of an actual threshold voltage of at least one monitor transistor. Performance improvements include improved reliability, wider operational bias conditions, reduced power consumption and (in the case of memory cells) improved retention time.

摘要： A charge pump generator system and method is provided which more precisely maintains the level of an internally generated voltage supply by operating some or all of the available charge pumps depending upon the voltage level reached by the voltage supply. When the voltage supply is far from its target level, a first group and a second group of charge pumps are operated. The first group may preferably have a faster pumping rate or a greater number of charge pumps than the second group. When the voltage supply exceeds a first predetermined level, the first group of charge pumps is switched off while the second group remains on, such that the rate of charge transfer slows. The second group continues operating until a second, e.g. target, voltage level is exceeded. The slower rate of charge transfer then effective reduces overshoot, ringing and noise coupled onto the voltage supply line. Preferably, at least one charge pump operates in both standby and active modes, thereby reducing chip area.

摘要： A charge pump generator system and method is provided in which on or more charge pumps are operated at multiple charging rates depending upon the level reached by a voltage supply. The system includes a limiter which provides a control signal based upon the level of the voltage supply. The control signal selects the frequency of a multiple frequency oscillator coupled thereto. The selected frequency determines the charge transfer rate of a charge pump used to maintain the voltage supply.

摘要： Apparatus is used to dynamically control the power output of generators (16A-16H) of a generator system on a chip (10) to load circuits on the chip. A power bus (14) is directed along at least one 'spine' section (18) on the chip which may intersect with at least one 'arm' section (19) on the chip for supplying power from the generators, which are coupled to the power bus in the 'spine' section thereof, to the load circuits on the chip. The power bus has a feedback lead (32) from each end which is remote from the generators for providing a continuous measurement of a voltage drop occurring at each remote end. At least one detector circuit (100) is located at a predetermined point adjacent the generators of the chip for comparing a voltage from the generators measured at the predetermined point with the concurrent voltage drop measured at an associated remote end. In response to such comparison, the at least one detector circuit generates control signals (BOOST and SPEED) for transmission to the generators for altering a generated voltage to maintain a predetermined power level on the power bus in response to load changes caused by the circuits on the chip.

摘要： In a controller for controlling a generator system on a memory chip, the controller operates as a state machine in accordance with a state diagram including a plurality of X states. An evaluation arrangement evaluates a combination of only a predetermined one of a plurality of N input signals from remote devices, and only a predetermined one of a plurality of X state signals indicating a current state in the state diagram at any instant of time. The controller generates a plurality of Y output signals having a predetermined logical value that indicates that a change from one state to a next state in the state diagram is to be made when the predetermined one of both the plurality of N input signals and the plurality of X state signals comprise a predetermined logical value. A state storage device is responsive to the predetermined one of a plurality of Y output signals having a predetermined logical value, and generates a revised plurality of X state output signals for transmission back to the evaluation arrangement indicating a change in the state diagram from a current state to a next state of the plurality of X states. An output arrangement is responsive to the revised plurality of X state output signals for generating separate predetermined ones of M output signals to remote devices associated with said next state for controlling the generator system.

摘要： A circuit for storing a bit of data is provided, where the circuit includes a first fuse having a first end and a second end and a second fuse having a third end and a fourth end. The first end of the first fuse is connected to a logic 0 input and its second end is connected to a common output. The third end of the second fuse is connected to a logic 1 input and the fourth end is connected to the common output. To store the bit of data, one of the first and second fuses is selectively blown. Hence, two fuses can be used to store a bit of information.

摘要： A voltage pump system for programming fuses on a semiconductor chip, in accordance with the present invention, includes a first pump system (12) employing a supply voltage (VDD) of the semiconductor chip as an input. The first pump system supplies an output voltage (VPP) higher than the supply voltage on a first output line (16) without raising the supply voltage of the semiconductor chip. A second pump system (20) includes an input connected to the first output. The second pump system supplies an output voltage (VFuse) sufficient for programming electrical fuses on the semiconductor chip.
