摘要： The cancellation of a redundant element of an integrated circuit with a cancel bank is disclosed. In one embodiment, a fuse or antifuse bank is coupled to the redundant element and permanently programmed to respond to the address of a defective primary element. If the redundant element is found to be defective, the fuse or antifuse bank is canceled, and a result the redundant element is also canceled. A cancel line of the fuse or antifuse bank, along with the cancel line of each of a plurality of other fuse or antifuse banks, is coupled to a cancel bank. The cancel bank comprises a multiplexer and a plurality of cancel antifuses less in number than the number of fuse or antifuse banks. The cancel antifuses are selectively enabled such that the fuse or antifuse bank coupled to the defective redundant element may be canceled.

摘要： As part of a memory array, a circuit is provided for altering the drive applied to an access transistor that regulates electrical communication within the memory array. In one embodiment, the circuit is used to alter the drive applied to a sense amp's voltage-pulling transistor, thereby allowing modification of the voltage-pulling rate for components of the sense amp. A sample of test data is written to the memory array and read several times at varying drive rates in order to determine the sense amp's ability to accommodate external circuitry. In another embodiment, the circuit is used to alter the drive applied to a bleeder device that regulates communication between the digit lines of the memory array and its cell plate. Slowing said communication allows defects within the memory array to have a more pronounced effect and hence increases the chances of finding such defects during testing. The circuit is configured to accept and apply a plurality of voltages, either through a contact pad or from a series of discrete voltage sources coupled to the circuit.

摘要： A programmable circuit includes a first node and provides a programmed signal based on the state of the first node. A first anti-fuse has a programmed state and an unprogrammed state and couples the first node to a first power supply when in the programmed state and decouples the first node from the first power supply when in the unprogrammed state. A second anti-fuse has a programmed state and an unprogrammed state and couples the first node to a second power supply when in the programmed state and decouples the first node from the second power supply when in the unprogrammed state. The state of the programmed signal can be used to replace a primary circuit element of an integrated circuit with a redundant circuit element.

摘要： An antifuse bank includes a bank of self-decoupling anti fuse circuits. The anti fuse circuits are programmed according to a pattern of address bits by blowing antifuses corresponding to bits of the address. The antifuses are blown by applying a high voltage across the antifuse. As each antifuse is blown, its resistance drops and current through the antifuse increases. The self-decoupling circuit detects the increased current flow and, when the anti fuse resistance is sufficiently low, limits current flow through the anti fuse. The antifuse thus does not load the high voltage source as other antifuses are blown.

摘要： Semiconductor memory devices having recessed access devices are disclosed. In some embodiments, a method of forming the recessed access device includes forming a device recess in a substrate material that extends to a first depth in the substrate that includes a gate oxide layer in the recess. The device recess may be extended to a second depth that is greater that the first depth to form an extended portion of the device recess. A field oxide layer may be provided within an interior of the device recess that extends inwardly into the interior of the device recess and into the substrate. Active regions may be formed in the substrate that abut the field oxide layer, and a gate material may be deposited into the device recess.

摘要： The invention includes methods of forming channel region implants for two transistor devices simultaneously, in which a mask is utilized to block a larger percentage of a channel region location of one of the devices relative to the other. The invention also pertains to methods of forming capacitor structures in which a first capacitor electrode is spaced from a semiconductor substrate by a dielectric material, a second capacitor electrode comprises a conductively-doped diffusion region within the semiconductor material, and a capacitor channel region location is beneath the dielectric material and adjacent the conductively-doped diffusion region. An implant mask is formed to cover only a first portion of the capacitor channel region location and to leave a second portion of the capacitor channel region location uncovered. While the implant mask is in place, dopant is implanted into the uncovered second portion of the capacitor channel region location.
