The driver comprises a pull up transistor for switching the output of the driver to a high-voltage, a pull down transistor for switching the output of the driver to a low voltage, a first current mirror transistor coupled to the pull up transistor for controlling the current transmitted to a load connected to the driver when the output of the driver is at the high-voltage, and a second current mirror transistor coupled to the pull down transistor for controlling the current transmitted to the load when the output of the driver is at the low voltage. In addition, the driver may include a first pre-driver providing a gate signal for the pull up transistor having a controlled slew rate and a second pre-driver providing a gate signal for the pull down transistor having a controlled slew rate.

    摘要: A circuit for programming electrical fuses, in accordance with the present invention, includes a shift register including a plurality of latches. Each latch has a corresponding switch and a corresponding electrical fuse. A bit generator generates a single bit of a first state and all other bits of a second state. The bit generator propagates the generated bits into the shift register in accordance with a clock signal. Each switch enables conduction through the corresponding electrical fuse in accordance with the generated bits stored in the corresponding latch. A blow voltage line connects to the electrical fuses. The blow voltage line is activated to blow fuses in accordance with programming data such that the electrical fuses are programmed in accordance with the programming data when the single bit of the first state is stored in the latch corresponding to the fuse to be programmed.

    摘要: Address information representing failed elements in an array portion of a device is delivered. Respective fail address bit values are stored in a plurality of fuses. A signal associated with a respective value of a portion of a further address is received. When the signal is received, one of the fail address bit values is delivered from one of the fuses to a corresponding latch circuit. The latch circuit receives fail address bit values from at least two of the fuses. One of the fail address bit values is selected based on the value associated with the signal. The latch circuit is activated to deliver the fail address bit value.
