    Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for locking and unlocking of an adaptive cache frame. SOLUTION: A frame that has been most accessed of late in a cache memory is possible to be accessed again by a task in the near future. By locking these frames that have been most used at the start of switch or interrupt of a task, the cache performance is improved. The list of frames that have been most used of late is updated as the task is executed, and the list is realized as a list of frame addresses or a flag related to each frame. An adaptive frame unlocking mechanism is also disclosed that automatically unlocks a frame being a potential primary factor of remarkable performance deterioration for a task. The adaptive frame unlocking mechanism monitors the number of times of frame errors that the task makes, and, if the number of times of frame errors exceeds a given threshold, unlocks a given frame.

    Abstract: PROBLEM TO BE SOLVED: To provide a comparator with non-complementary input structure in order to improve technical problems such as power consumption, number of transistors and a throughput delay in a conventional comparator circuit with a complementary input structure.
    SOLUTION: The non-complementary comparator includes an evaluation element such as a memory cell, a differential amplifier, or another type of circuit capable adapted to perform an evaluation function, and at least first and second input legs each coupled to a corresponding one of a first and second node of the evaluation element. However, after the evaluation, the output attains a full digital value but suffers no defective power consumption. Transistors form a cross coupling random access memory cell and perform a comparison of contents of the two legs during the evaluation.

    Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device which is manufactured by the use of organic material having bipolar charge transfer characteristics. SOLUTION: The active layer of a field-effect transistor is formed of organic semiconductor material having bipolar charge transfer characteristics. The semiconductor material is formed of a bipolar polymer film which is effective for the transfer of holes or electrons, containing polymer that has a conjugate skeleton stare possessed of a functional part capable of promoting the transfer of ionic charge. The conjugate skeleton is selected out of thiophene, pyrrole, benzene, naphthalene, anthracene and anthracene-dione, and the functional part is selected out of (i) a functional group containing calboxylate and sulfonate and (ii) a functional site selected from dissimilar atoms provided with isolated electron pairs, containing sulfur, nitrogen, and oxygen. The field effect mobility of the bipolar polymer film is, at least, as high as 10-3 cm2/Vs when it operates as an N-type or a P-type device.

    Abstract: PROBLEM TO BE SOLVED: To provide a method of forming Pb-free solder bumps with improved mechanical properties and to provide a semiconductor device using the same.SOLUTION: There is provided a semiconductor substrate having a first contact and an undoped electroplated lead-free solder bump 610 formed on the first contact. There is also provided a device package substrate having a second contact and a doped lead-free solder layer 510 containing dopant on the second contact. The dopant reduces a solidification undercooling temperature of the undoped lead-free solder bump when the dopant is incorporated into the lead-free solder bump. The undoped electroplated lead-free solder bump and the doped lead-free solder layer are melted thereby incorporating the dopant into the undoped lead-free solder to form a doped solder bump 140. The solder bump provides an electrical connection between the first contact and the second contact.
