    摘要： A wrench includes a handle portion and a head portion coextensively connected with the handle portion. The head portion of the wrench has opposing flat surface faces and first and second jaw portions defining a substantially arcuate crescent interior of the wrench head. A slot is formed in the first jaw portion, the slot having a hole formed at a base end thereof through the head portion for access from an external peripheral surface of the head portion. A block member is slidably received within the slot, the block member including a base end and an exposed end, the exposed end protruding into the open crescent area, and a threaded hole formed in the base of the block member. A coiled spring is positioned between a base end of the block member and the base end of the slot, and a screw having a shank and a threaded tip at one end of the shank is inserted into the base of the block via the hole formed at the base of the first jaw portion, through the coiled spring, and is secured by engaging the threaded portions of the screw and the block. A securing bracket prevents displacement of the block member from the slot. The block member is adjustable to the extent that the spring compresses and otherwise functions as if it were integrally formed with the first jaw portion of the wrench head.

    摘要： A burn-in stress circuit for a semiconductor memory device. A burn-in enable signal generator generates a burn-in enable signal in response to a plurality of control signals. A wordline predecoder generates a wordline driving voltage for driving a wordline in response to the burn-in enable signal and another a plurality of control signals. A wordline decoder applies the wordline driving voltage to the wordline in response to the burn-in enable signal and another plurality of control signals. To reduce the stress testing time by stressing multiple rows of a memory array simultaneously, all of the wordlines (rows) are stressed and or tested at the same time. To select all of the wordlines, the wordlines are selected sequentially, but each selected wordline is held in a selected state by a latching mechanism while all of the other wordlines are being selected as well. When all of the wordlines (or a desired subset) have been selected, the burn-in stress test begins.
