摘要:
A semiconductor configuration is described and has a temperature sensor, which measures a temperature of a semiconductor module. The measured temperature is provided to a control unit, so that the control unit can adapt a refresh cycle in the semiconductor module to the retention time corresponding to the measured temperature.
摘要:
A temperature sensor is integrated together with an integrated circuit on a chip, the sensor delivering a temperature-dependent measuring signal or at least emitting a signal when the chip temperature falls below a specific prescribed value. For such an eventuality, the chip includes a special circuit device thereon, by which a current flow is generated through a provided structure of electrical conductors that keeps the temperature of the integrated circuit above a prescribed minimum temperature.
摘要:
Using site-directed mutagenesis to mutate the Xanthomonas campestris pectate lyase gene, variants of Xanthomonas campestris pectate lyase with improved thermostability and/or enzymatic activity have been expressed in Escherichia coli, and then isolated and purified. The mutant Xanthomonas campestris pectate lyases are more effective than the wild-type enzyme, also expressed in E. coli, in removing pectic compounds from natural hemp fiber.
