Abstract: PURPOSE: A real-time magnetic/adaptive interference noise removal apparatus and method thereof are provided to remove interference noise entered through a receiving antenna of a radio communication system by using a feedback method. CONSTITUTION: An RF(Radio Frequency) signal extractor(202) divides a received RF signal into a ratio.

IPC: H01L27/08
Filed: 2001-08-31
Abstract: PURPOSE: A method for manufacturing a semiconductor device is provided to suppress the occurrence of crystal defects that reach a semiconductor layer of an element region due to the stress concentration because an oxide film of a trench corner part becomes thinner in oxidation for the trench side wall when a trench element isolation structure is applied using an SOI substrate. CONSTITUTION: A region that becomes the element isolation region is formed by penetrating a substrate surface part(103) and then a groove is formed to the depth to reach a first insulating layer(104). A second insulating layer(110) is formed by a vapor phase growth method at the inside of the groove. A buried layer(111) is formed via the second insulating layer(110) to the inside of the groove, and a third insulating layer(112) is formed so as to cover the buried layer(111). As a result, because the oxidation layer by thermal oxidation is not formed at the side of the groove, the thermal oxidation step that induces the crystal defects becomes unnecessary, and thus the occurrence of the crystal defects in a step for forming a trench type element isolation can be restrained.

Title: Multi-port memory based on dram core
Inventor: KAMATA SHINNOSUKE
IPC: G11C7/10
Filed: 2001-10-26
Abstract: PURPOSE: Even if same memory block is simultaneously accessed by a plurality of ports, a BUSY state is not generated because the internal memory can attend to consecutive and continuous processing at double the speed. CONSTITUTION: At timing(C1) of an external command cycle relevant to the A port, a Read command is entered at the A port. Further, at timing(C1') of an external command cycle relevant to the B port, a Read command is entered at the B port. Since timing of the Read command of the A port is slightly earlier, this Read command is performed ahead of the Read command entered at the B port Here, one external command cycle corresponds to four clock cycles. Each Read command is executed and completed in two clock cycles that correspond to one core operation cycle. Accordingly, in response to the Read commands entered at the A port and the B port at the intervals of four clock cycles that are equivalent to one external command cycle, read operations can be performed without generating a BUSY state even if the read access from the A port and the read access from the B port are directed to the same block. This is achieved by carrying out and completing each access in two clock cycles.
