摘要:
A memory array having memory cells comprising a diode and an antifuse can be made smaller and programmed at lower voltage by using an antifuse material having a higher dielectric constant and a higher acceleration factor than those of silicon dioxide, and by using a diode having a lower band gap than that of silicon. Such memory arrays can be made to have long operating lifetimes by using the high acceleration factor and lower band gap materials. Antifuse materials having dielectric constants between 5 and 27, for example, hafnium silicon oxynitride or hafnium silicon oxide, are particularly effective. Diode materials with band gaps lower than that of silicon, such as germanium or a silicon-germanium alloy, are particularly effective.

A memory cell is provided that includes a diode and a resistance-switching material layer coupled in series with the diode. The resistance-switching material layer: (a) has a dielectric constant in the range of about 5 to about 27, and (b) includes a material from the family consisting of XvOw, wherein X represents an element from the family consisting of Hf and Zr, and wherein the subscripts v and w have non-zero values that form a stable compound. Other aspects are also provided.

摘要:
A method and apparatus for programming a memory array are disclosed. In one embodiment, after each word line is programmed, an attempt is made to detect a defect on that word line. If a defect is detected, the word line is repaired with a redundant word line. The word lines are then reprogrammed and rechecked for defects. In another embodiment, after each word line is programmed, an attempt is made to detect a defect on that word line. If a defect is detected, that word line is repaired along with a previously-programmed adjacent word line. In yet another embodiment, after each word line is programmed, an attempt is made to detect a defect on that word line and a previously-programmed adjacent word line. If a defect is detected on that word line, that word line and the previously-programmed adjacent word line are repaired with redundant word lines.

摘要:
A bolt locking structure for a waterproof LED lamp contains: a first casing and a second casing. The first casing includes multiple first protrusions and multiple first recesses which are arranged on each of four peripheral walls thereof respectively. The second casing includes multiple second protrusions and multiple second recesses which are arranged on each of four peripheral walls thereof respectively. The multiple first protrusions retain with the multiple second recesses, and the multiple first recesses retain with the multiple second protrusions. Multiple through holes are coaxial and form on each peripheral wall of each of the first casing and the second casing respectively, wherein each of the multiple through holes passes through each of the multiple first protrusions and the multiple second protrusions, such that each of multiple connection bolts inserts into the multiple through holes, thus locking the first casing and the second casing together.
