R8A20211BG/R8A20210BG (MARIE_Blade)
Network Address Search Engine
(9 M/18 M-bit Full Ternary CAM)
REJ03H0001-0100
Rev.1.00
Feb 21, 2005
Description
Renesas delivers MARIE_Blade that is a ternary CAM search engine targeted for network packet classifying. The full-
custom 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 288-
bit 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.
