Title: Memory error logger for distinguishing solid error from transient error
Inventor: SUPERI YUNIBATSUKU DEIRU KENIS
IPC: G06F12/16
Filed: 1978-12-02
Abstract: A method of and an apparatus for distinguishing between transient and solid errors within a single-error-correcting semiconductor memory storage unit (MSU) comprised of a plurality of large scale integrated (LSI) bit planes and for notifying the associated data processing system of required maintenance action. The method utilizes an error logging store (ELS) that is comprised of a plurality of memory error registers one for each separately associated word group within the MSU. Each memory error register contains storage for: (1) the Error Correction Code (ECC) defined, failing bit position; (2) the single bit error counter; (3) the multiple single bit error tag; and (4) the multiple bit error tag. Upon detection of an error within a word group, the associated memory error register is accessed to determine the history of previously detected errors within that word group. The central processing unit (CPU) is notified by a priority interrupt of the error status of that word group if: (1) the number of consecutive errors within a word group at the same bit position reaches a set threshold indicating the high probability of a solid single bit error; or (2) the error detected is in a different bit position from that previously identified as a solid single bit error indicating the high probability of a future uncorrectable multiple-bit error. This method and apparatus notifies the CPU of the likelihood of imminent uncorrectable errors and maintains a history of the error indications that lead to that conclusion.

Abstract: PURPOSE:To finish selection for constant weight packaging and to increase selection efficiency by setting the total number of times of discharge and total discharge weight which has a constant permissible difference. CONSTITUTION:The total number (for example, 6) of times of discharge and the total discharge weight having the constant permissible difference are set, and every (n)th cumulative target weight having a specific permissible difference is preset up to the total number (6 in this case) of times of discharge. Then it is judged that articles 2 after being weighed by a weigher 3 are expected to be discharged when within the range of preset (n)th cumulative target weight. When a specific state continues specific times, on the other hand, the weight value of the articles to be discharged is calculated from (discharge weight)/(number of times of discharge). Consequently, the weighed value of articles which are determined to be discharged, but still not discharged and in the middle of the conveyance on a distribution conveyor 1 is compared with the calculated weight value to select the weighed value having the largest difference; and the discharge of articles corresponding to the value is canceled and they are regarded as objects of redecision making.

IPC: H01L21/316
Filed: 1985-07-10
Abstract: PURPOSE:To prevent generation of gas by reaction of base layer and impurity layer during reflow even when the base layer is active by lowering impurity concentration of insulation layer region proximate to said base layer. CONSTITUTION:The As concentration of insulation layer 2 is not uniform, and the As concentration (impurity concentration) of the part (lower side) being in contact with a stopper layer 7 is zero or is lowered to such a degree as not allowing generation of HCl gas during the heat processing. Namely, the insulation layer 2 is formed by a low concentration layer 2a with a thin As concentration and a high-concentration layer 2b for reflow with thick As concentration. For example, in the case of reflow at 900 deg.C, the HCl gas is generated with an amount of 18-19wt% but when concentration becomes high, gas is yet generated even under the lower temperature. Concentration which can certainly prevent generation of gas can be estimated as 0-15wt%. The upper limit of concentration for impurity to be doped is generally 30-40w% in the case of AsSG.
