Overview
R8A20211BG/R8A20210BG (MARIE_Blade) Network Address Search Engine (9 M/18 M-bit Full Ternary CAM) REJ03H0001-0100 Rev.

00 Feb 21, 2005 Description Renesas delivers MARIE_Blade that is a ternary CAM search engine targeted for network packet classifying.
The fullcustom CAM memory realizes large capacity, high density and low power consumption.
www.
DataSheet4U.
com MARIE_Blade can realize up to 133 Msps in 72-bit/144-bit normal mode (parallel search 266 Msps), 66.
5 Msps in 288bit mode (parallel search 133 Msps) and 33 Msps in 576-bit mode (parallel search 66.
5 Msps).
The Hierarchical search reduces power consumption; The DX test logic, an extended bit, performs a DX test logic search first (primary search), and the DQ pin performs a DQ array search (secondary search).
The parity bit in the DQ array can check for errors as an additional function.
