摘要： By using a small number of needles and contact terminals at burn-in, electric contact check is performed between each needle and each terminal provided in each semiconductor chip, and thereby the yield of assembled products can be improved. A packaging structure in which, for example, a volatile memory chip and a nonvolatile memory chip are formed is assembled in accordance with a production scheme in which burn-in of each memory chip is performed while still under the state of a semiconductor wafer, and by forming the packaged structure using the good volatile memory chip subjected to burn-in and likewise, also, the nonvolatile memory chip. At this burn-in, contact check is performed by bringing a needle, provided in a burn-in board, into contact with, for example, six test-only signal terminals of a test circuit formed on each semiconductor chip.

摘要： A sense amplifier, which is intended to reduce the output response time after it has received a small voltage difference until it delivers amplified output signals, consists of a latch circuit made up of a pair of CMOS inverters, a pair of NMOS transistors connected in parallel to the latch circuit, and a current source connected in series to the latch circuit and NMOS transistor pair. The NMOS transistors amplify a small voltage difference of input signals, and the inverters of the latch circuit further amplify the resulting voltage difference to produce the output signals. Based on a small voltage difference of input signals being amplified in two stages and the amplifying circuit being 2-stage serial connection of the current source and the NMOS transistor or CMOS inverter, the delay time of output response can be reduced.

摘要： A Synchronous Dynamic Random Access Memory (SDRAM) has its operation mode selected to be the Single Data Rate (SDR) mode in response to the first state of the external terminal (OPT), thereby releasing data, which has been read out of a memory mat, in response to a clock signal produced by a clock regenerating circuit having a function of comparing the phases of the input and output of the circuit, or selected to be the Double Data Rate (DDR) mode in response to the second state of the external terminal (OPT), thereby releasing data, which has been read out of the memory mat, in response to a clock signal produced by a clock signal generation circuit in synchronism with an external clock. In the SDR mode, data are transferred via data lines in SDRAM unidirectionally and in the DDR mode, data are transferred via the data lines bidirectionally.

摘要： An objective is to provide a pressure-contact type rectifier in which solder that increases the environmental load is not used, and neither burning nor breakage of a rectifying device occurs, even if temperature of the rectifying device increases due to current flowing or force towards outside the rectifying device is applied to a lead end, etc. By providing an electrically conductive friction reducer on at least one electrode face of the rectifying device, the temperature increase can be prevented, and the friction at the contact face can be reduced. Moreover, by providing a flexible portion on the lead end outside a cap, and fixing the flexible portion to the cap, the contact area between the lead and the rectifying device can be kept constant. As a result, a pressure-contact type rectifier in which neither burning nor breakage of the rectifying device occurs can be obtained.
