    摘要: A semiconductor memory array with Built-in Self-Repair (BISR) includes redundancy circuits associated with failed row address stores to drive redundant row word lines, thereby obviating the supply and normal decoding of a substitute addresses. NOT comparator logic compares a failed row address generated and stored by BISR circuits to a row address supplied to the memory array. A TRUE comparator configured in parallel with the NOT comparator simultaneously compares defective row address signal to the supplied row address. Since NOT comparison is performed quickly in dynamic logic without setup and hold time constraints, timing impact on a normal (non-redundant) row decode path is negligible, and since TRUE comparison, though potentially slower than NOT comparison, itself identifies a redundant row address and therefore need not employ an N-bit address to selected word-line decode, redundant row addressing is rapid and does not adversely degrade performance of a self-repaired semiconductor memory array. By providing redundancy handling at the predecode circuit level, rather than at a preliminary address substitution stage, access times to a BISR memory array in accordance with the present invention are improved.

    摘要: An architecture for a semiconductor static random access memory (SRAM) is described. In one example, a first set or group or stage of SRAM banks are coupled to a first data bus formed using bit line pairs, and a second set or group or stage of SRAM banks are coupled to a second data bus formed using other bit line pairs. The number of banks coupled to each bit line pair is determined by the SRAM's operating frequency and size. Each data bus is coupled to a sense amplifier. The output from the sense amplifier is then coupled to the bit line pair of a group of SRAM banks. This adjacent group has staging logic coupled to each SRAM bank to store the output of the SRAM bank until the contents from the first group is placed on the bit line of the adjacent stage of SRAM banks. The output from either the first stage or from one of the SRAM banks in the adjacent stage's SRAM banks, which had been stored in the adjacent stage's staging logic, is driven to the sense amplifier coupled to the adjacent stage. Successive stages of SRAM banks can be coupled together until an arbitrary number of stages of SRAM banks have been coupled together.

    摘要: A method of rendering a surface of a metal substrate substantially acid impervious. The method includes first placing the surface in a field of treatment, then depositing a mixture of a high-temperature resistant polymer particulate such as polyamide particulate and a curable powder adhesive on the surface, and finally subjecting the surface-coated metal substrate to a curing treatment sufficient to cure the powder adhesive and thereby adhere the polymer particulate as a film on the surface. A steel substrate coated in accord with the present methodology is particularly useful as a curing fixture upon which resin-impregnated fiber of polymer composite material is placed to thereby give molded parts made therefrom a desired shape. Production of a part is accomplished by vacuum bagging the composite material to the steel fixture and curing the so-produced part in place on the fixture in an autoclave at an elevated temperature. In this manner the acid impervious curing fixture allows production of composite parts without the danger of leaching iron from the fixture to thus assure full-utility part fabrication.
