Title: Semiconductor storage device
Inventor: HARA KOJI
IPC: G11C11/413
Filed: 1991-03-19
Abstract: PURPOSE:To reduce power consumption and to enable a long duration backup by backing up dynamic RAMs with a lower than normal operating voltage during a device power supply off. CONSTITUTION:When the device power supply is turned off and a power supply voltage VCC becomes low, a voltage VEXT of dynamic RAM2 becomes low. When the voltage VEXT is lowered to battery voltage VBAT minus a voltage drop at a diode 42, the voltage VBAT is supplied to the RAM2 and a control circuit 1 through the diode 42. Since the voltage VBAT is lower than the operating voltage, a low voltage is supplied to the voltage VEXT. And the refresh operations continue to protect the data of RAM2. However, the power consumption is smaller due to the lower voltage. Furthermore, when a detecting signal SENS is activated through the detection of lowering voltage VCC, a refresh period and a CAS before RAS mode timing are generated in the circuit 1.

Abstract: PURPOSE:To improve the sensitivity of specific agglutination in a reagent for measuring an antigen and antibody by an agglutination reaction of agglutination inhibition reaction by treating an antibody or hapten-deltaglobulin composite sensitized with a carrier with a specific compd. CONSTITUTION:The reagent is produced by sensitizing the high-polymer antigen (protein, polypetide, etc.) and low-polymer hapten (steroid)-gammaglobulin composite with the carrier. A high polymer of pulverous particles, red blood cells, etc. are used for the carrier. The antibody, etc. are treated by bringing the same into contact with the specific compd., 2-mercaptoethanol, 2-mercaptoethylamine, thioglycolic acid, cysteine, dithiothreitol, dithioerythritol, etc. for a prescribed period in fore, middle and post processes for production, by which the antibody and composite are sensitized with the carrier. Since the reagent is obtd. in the above-mentioned manner, the non-specific agglutination inhibition reaction is suppressed even if extraneous materials are contained in the specimen. The agglutination or agglutination inhibition reaction is thus induced with good sensitivity and the reliability of the immunological measurement is improved.
