Title: Semiconductor memory
Inventor: TANAKA SHINJI
IPC: G11C29/50
Filed: 1989-11-10
Abstract: PURPOSE:To execute an operation margin test of a memory cell easily and to obtain the result of the test quickly by providing an additional capacitance connecting means, connecting it to a bit line pair when in a test mode, and making it equivalent to a stray capacitance increase. CONSTITUTION:Dummy capacitance 24, 25 with about five times the capacity of a memory capacitance 11 is connected to a bit line pair BL and -BL with a selection transistor 22, 23, and a cell plate voltage Vcp is given to one of the electrodes. When reading the test mode, to the control electrode, a test mode signal is generated from a control signal generation circuit 21 and connected to the bit line pair. At this time, it becomes equivalent to when the stray capacitance increases for the amount of the dummy capacitance. As a result, the contents of the memory cell is difficult to appear as a potential difference between the bit line pair when reading at the time of test mode, and the test mode cannot be read out normally when the operation margin of the memory cell is reduced, so the operation margin test of the memory cell can be executed easily, and the test result can be obtained quickly.

Filed: 1995-11-13
Abstract: PROBLEM TO BE SOLVED: To receive a call signal from a mobile station within an intermittent reception period by using two line frequencies so as to process call transmission from a mobile station to plural terminal stations and data communication from the terminal station to the mobile station in parallel. SOLUTION: In the case of collecting information from plural terminal stations by using a mobile station, a line frequency f1 is in use and a call signal being a data transmission request signal is sent to the plural terminal stations. A terminal station receiving the call signal selects a line frequency f2 to send data to the mobile station 1. Two channels of line frequencies are in use, then transmission of the call signal from the mobile station 1 and data transmission from each terminal station are processed in parallel. Thus, a time of collection of data of plural terminal stations from the mobile station 1 is reduced to a sum of a transmission delay time and a data transmission time.

Abstract: PURPOSE:To reduce junction capacitance as the easy takeoff of a base electrode is kept as it is, and to obtain excellent high-frequency characteristics by growing a base layer and an emitter layer in an epitaxial manner onto a partially exposed collector layer in succession again. CONSTITUTION:Collector layers 2, 3, a semi-insulating semiconductor layer 11 and a base layer 4 are formed onto a semi-insulating GaAs substrate 1. An SiO2 film 12 is shaped. One parts of the film 12, the layer 4 and the layer 11 are removed through etching, and one part of the layer 3 is removed. A base layer 5 and emitter layers 6, 7 are grown on the film 12 in an epitaxial manner in succession, and a semi-insulating polycrystalline film is formed to the upper section of the film 11 at that time. One part of the semi-insulating polycrystalline film is etched to expose one parts of the layer 4 and the layer 2. An emitter electrode 10, base electrodes 9 and collector electrodes 9 are each shaped to the layer 7 and the exposed layers 4 and layers 2. According to the method, emitter capacitance is proportional to the junction areas of the layer 6 and the layer 5 in a re-growth section. Consequently, the junction capacitance of the section can be ignored approximately, thus acquiring excellent high-frequency characteristics.
