摘要： A level shifter is presented that allows fast switching while requiring low power. In accordance with some embodiments of the invention, the level shifter is a two stage level shifting circuit with p-channel and n-channel transistors biased so as to limit the potential between the source to gate or drain to gate of any of the transistors. Pull-up transistors are placed in a transition state so that spikes resulting from an increasing or decreasing input voltage turn on or off the pull up transistors to assist in the switching.

摘要： An integrated circuit delay device includes a digital delay line configured to provide a percent-of-clock period delay to a timing signal received at an input thereof, in response to a control signal. This control signal has a value that specifies a length of the delay. A delay line control circuit is also provided. The delay line control circuit is configured to generate the control signal by counting multiple cycles of a high frequency oscillator signal (e.g., ring oscillator signal) having a period less than the clock period, over a time interval having a duration greater than the clock period.

摘要： Flip-flops include a master stage and a slave stage. The master stage is responsive to a first clock signal and has a first pair of differential inputs and a first pair of differential outputs. The slave stage is responsive to a second clock signal and has a second pair of differential inputs coupled to the first pair of differential outputs and a second pair of differential outputs from which true and complementary outputs (Q, QB) of the flip-flop are derived. If the flip-flop is a D-type flip-flop, the first pair of differential inputs receive true and complementary data signals (DATA, DATAB). If the flip-flop is a set-reset (S-R) flip-flop, the first pair of differential inputs receive set and reset signals (SET, RESET).

摘要： A circuit improves the reliability of antifuses in certain types of systems by substantially eliminating the continuous undesirable applications of voltages across antifuse terminals. To accomplish this, an antifuse has applied across its two terminals a "reading" or "evaluation" voltage as required by the system operation for a single read or evaluation clock period (typically 5 ns to 30 ns in duration). The signal describing the state of the antifuse is then stored in a latch, register, or other suitable structure for subsequent sampling. In this manner, a low read current flows in the antifuse in response to the standard chip operating voltage for only a short period of time such as a single clock cycle. Thus, continuous voltages across the two terminals of the antifuse are avoided and an unprogrammed antifuse is not inadvertently programmed and a programmed antifuse is not inadvertently converted back to its high impedance state (i.e. "unprogrammed"). In another embodiment, a multiplexer coupled to a terminal of the antifuse switches the terminal of the antifuse to a programming voltage node when the antifuse is selected for programming and to a reference voltage source when the antifuse is not selected for programming. The multiplexer prevents undesired voltages from being applied across the antifuse while other antifuses are being programmed. The two embodiments discussed may be used in conjunction with each other or separately.

摘要： A redundancy circuit for a semiconductor memory device utilizes a fuse ladder comprising alternating programmable resistive fuses and signal restorers connected to one another in series. The signal restorers coupled between the fuses prevent the formation of a high impedance resistive line with a floating node when one of the fuses in the ladder is blown.

摘要： An antifuse redundancy circuit operates with transparency to external circuitry and users. In one embodiment, an antifuse redundancy circuit incorporates two antifuses rather than one. The circuit is arranged so that both antifuses may be simultaneously programmed and read. If a single antifuse is programmed without programming the other antifuse, the antifuse redundancy circuit will register a programmed antifuse. Additionally, if a single programmed antifuse is unintentionally deprogrammed after both antifuses in the redundancy circuit have been programmed, the antifuse redundancy circuit will continue to register a programmed antifuse. The result is both an increase in manufacturing yield and an increase in the reliability of integrated circuits utilizing antifuses.
