Ternary content-addressable memory (TCAM) has become popular in high-speed lookup intensive applications. Large dynamic power consumption of TCAMs makes power reduction techniques an active area of research. In this paper we present a new match-line (ML) sensing scheme employing ML segmentation and positive feedback in the sense amplifier of the first segment. Simulation using 130nm 1.2V CMOS logic...
This paper presents a match-line architecture to reduce the energy consumption of Ternary content-addressable memory (TCAM) and to increase search speed. The proposed match-line (ML) sensing scheme uses a two-step comparison to filter out most of the mismatched MLs in the first step so that the second step comparison is never activated for those mismatched MLs. Simulation using 130-nm 1.2-V CMOS logic...
Shallow trench isolation schemes using a LOCOS edge to avoid sharp corner effects are applied to 0.25 /spl mu/m and 0.18 /spl mu/m technologies. Two variations are studied. In the first case (Case A) a mini-LOCOS is grown and deglazed prior to trench etch whereas in the second case (Case B) the deglaze is omitted. Excellent narrow width effect is demonstrated. The V/sub T/ increases by /spl les/50...
