    摘要: A memory chip design methodology is disclosed wherein fuse banks on the memory chip may be implemented without enable fuses. A fuse bank may be enabled by using one or more least significant bits (LSBs) in the memory address stored in the fuse bank, thereby avoiding the need for a separate enable fuse. A reduction in the number of fuses results in space savings on the memory chip real estate and also savings in power consumption because of fewer fuses to be blown and read. With reduced fuse count, the yield of the memory chip's die may also be improved because of less number of defective fuses or failed fuse blows. The use of effective default state inversion for address fuses may further reduce the average number of fuses that need to be blown to repair a given non-redundant memory address. Because of the rules governing abstracts, this abstract should not be used to construe the claims.

    摘要: Techniques for controlling a driver to reduce data dependent noise, such as simultaneous switching effects and cross-talk effects. A plurality of drivers may each receive a data segment to transmit and a plurality of data segments that other drivers will transmit. A driver controller may adjust the time at which the data segment is transmitted in response to the plurality of data segments that the other drivers will transmit. The adjustment may compensate for simultaneous switching noise and cross-talk by, for example, delaying the transmission of a data segment or changing the slew rate of the signal carrying the data segment.

    摘要: An input buffer having a comparator that receives an input signal, a reference signal and a positive feedback. The comparator compares the input signal relative to the reference signal and generates an output signal transitioning between a first logic state and a second logic state responsive to the magnitude of the input signal transitioning through the magnitude of the reference signal. The comparator intensifies the output signal in response to the positive feedback from the output of the comparator while the output signal transitions from the first logic state to the second logic state.

    摘要: An antifuse latch device and method for performing a redundancy pretest without the use of additional test circuitry is disclosed. Conventional antifuse latch devices are designed such that a redundancy pretest cannot be performed on the antifuse latch device once the antifuses are programmed but rather requires additional circuitry to map the appropriate address bits to test the redundant row or column. The present invention adds a level translating inverter to a conventional antifuse latch device, thus allowing the antifuse latch device to simulate an unblown antifuse by isolating the antifuse from the latch.

    摘要: A lower current input buffer is used for waking up a plurality of higher-current buffers. The lower current buffer monitors a wake-up signal and, when present, enables the higher current buffers. A higher current buffer is used to detect the sleep mode and disable the higher current buffers. A delay circuit may be used to balance the propagation delay through the circuit.

    摘要: A method and system for operating a DRAM device in either a high power, full density mode or a low power, half density mode. In the full density mode, each data bit is stored in a single memory cell, and, in the half density mode, each data bit is stored in two memory cells that are refreshed at the same time to permit a relatively slow refresh rate. When transitioning from the full density mode to the half density mode, data are copied from each row of memory cells storing data to an adjacent row of memory cells. The adjacent row of memory cells are made free to store data from an adjacent row by remapping the most significant bit of the row address to the least significant bit of the row address, and then remapping all of the remaining bits of the row address to the next highest order bit.

    摘要: A method of operating a delay locked loop is comprised of producing a first output signal in response to a first lock point. A new lock point is measured, or otherwise determined, while continuing to produce the first output signal. Thereafter, a second output signal is produced in response to the new lock point. The new lock point data may be loaded into the delay locked loop while the delay locked loop continues to produce the first output signal. The delay locked loop switches from producing the first output signal, responsive to a first lock point, to producing the second output signal, responsive to the new lock point, in response to various conditions such as control signals, e.g. an auto refresh command, a precharge all command, a mode register load command, a power down entry, a power down exit (among others), in response to a timer, e.g., an internal timer (among others), or in response to environmental condition signals, e.g., a temperature sensor output signal (among others). Circuits and systems using the disclosed method are also disclosed. Because of the rules governing abstracts, this abstract should not be used to construe the claims.
