Abstract: In a method of forming a metal-insulator-metal (MIM) capacitor in a semiconductor device, after forming a capacitor insulation layer on a lower metal layer of the MIM capacitor, an upper electrode is formed by ion implantation into the capacitor insulation layer and silicidation, without a typical reactive ion etching process. Consequently, damage to the capacitor insulation layer can be minimized, and the area of the capacitor need not increase.

Abstract: A rate 7/8 MTR code encoding/decoding method and apparatus. The encoding method includes: generating a rate-7/8 MTR code for inputting 7-bit data and outputting a predetermined 8-bit codeword; checking whether codewords satisfy a predetermined constraint condition by connecting the 8-bit codeword and a subsequent 8-bit codeword; and if the codewords do not violate the constraint condition, not converting the codewords. The decoding method includes: checking whether the codewords satisfy a predetermined MTR constraint condition by connecting a current 8-bit codeword c(k) and a subsequent 8-bit codeword c(k+1); if the codewords violate the constraint condition, converting the codewords, and if the codewords do not violate the constraint condition, not converting the codewords; and decoding each converted 8-bit codeword into 7-bit data using a predetermined MTR code. Data is reliably reproduced with high write density, and large amounts of data are stored in and reproduced from a magnetic recording information storage medium.

Abstract: An apparatus and method for adaptively adjusting a target Received Signal Strength Indicator (RSSI) for Automatic Gain Control (AGC) in a full-duplex relay apparatus with an interference cancellation function. A Signal to Interference Ratio (SIR) estimation block estimates an SIR based on an interference signal estimated from a received signal and an interference-cancelled signal determined by cancelling the estimated interference signal from the received signal. A target RSSI determination block determines a target RSSI according to the estimated SIR. An AGC block adjusts a gain for the received signal based on the determined target RSSI.
