Title: Dynamic memory control system
Inventor: WATANABE TAKASHI
IPC: G11C11/406
Filed: 1992-06-11
Abstract: PURPOSE:To reduce power consumption by varying a refresh interval according to the surrounding temperature of a dynamic memory. CONSTITUTION:A temperature sensor 12 measures the surrounding temperature of a dynamic memory 11, and transmits it to a refresh request circuit 13 as temperature information signal (a). The request circuit 13 decides the maximum refresh interval permitted in the present surrounding temperature of the memory 11 obtained through the signal (a). Then, the request circuit 13 issues a refresh request to a memory control circuit 14 by a refresh request signal (b) in the decided refresh interval. The memory control circuit 14 arbitrates the request of the refresh request signal (b) and a memory access request signal (d), and operates the refresh control and access control of the memory 11 by a memory control signal (c).

Abstract: PURPOSE:To easily decide presence or absence of a redundancy technique use by composing a circuit in which a plurality of transistors commonly connected at gates and drains and fuses are disposed in series in an arbitrary order between a signal line and a ground wiring. CONSTITUTION:A plurality of MOS transistors 4a-4h connected commonly at gates and drains, a P-channel type MOS transistor 8 connected at its gate to a power source wiring 7, and a fuse 3 are disposed in series in an arbitrary order between a signal line 2 for transmitting the potential of input or output terminal and a ground wiring 5. Accordingly, since no current flows at a voltage of total voltage or less of threshold value voltages of the plurality of MOS transistors, no leakage current flows to a terminal with a normal input voltage even if a power source voltage is O v. Thus, the current value when a high voltage which is not normally used is applied to an input terminal 1 is measured to decide presence or absence of use of a redundancy circuit.

Abstract: PURPOSE: To allow the amplifier to deal with a temperature change by providing a temperature dependent means that controls signal amplification, so as to make the amplified signal independent of temperature to each of amplifier stages connected in cascade and providing a similar temperature dependent means that controls an overall output limit voltage, so as to make the amplified voltage independent of temperature for the final stage. CONSTITUTION: A negative feedback is applied to long-tailed transistors(TRs) 16, 18 in a pair with emitter resistors 22, 24 during the operation, the resistance is selected to prevent the limitation, and a linear gain is provided to the TR pair over an available input voltage to a concerned stage. In the series connection of amplifier stages of a similar configuration having a logarithmic transfer function, the gain of the amplifier of each stage is selected to be unity. Since no externally mounted emitter resistor is provided to the TRs 14, 20 in a pair, a high gain is obtained by the TRs 16, 18. However, when an input level is a threshold level or over, since the TRs 14, 20 are brought into a limit state, an emitter follower (not shown) is provided so as to relax an output to a succeeding load.  Thus, currents IT1, IT2 proportional to the absolute temperature are supplied from current sources 26, 28.

CONSTITUTION:In a flat heat-conductive tube 12a a partition plate 31 is placed at the center part of the tube inside in the tube axial direction for overall length of a straight tube part. The width of this partition plate is about same as the size L4 between two walls in a minor axis L1 and at its both edge parts, folded pieces 31a are formed and its flat wall part a number of turbulent flow plates 32 are cut and raised alternately in the upper and lower sides. Water flow is made turbulent by the turbulent flow plates 32 and flows in wave form as a whole and flow does not stagnate around the top of the turbulent flow plates 32. Therefore, heat transfer coefficient between tube walls and flowing water is increased and mal-distribution of temp. because of local heating in partial stagnant place of water flow does not occur. And, heat absorption amount by flowing water is increased and as a result, maximum temp. of fins is reduced.
