Description
“MARIE” is a new RENESAS Ternary CAM co-processor targeted for the network packet classification and signature
matching application. MARIE’s 1 M-bit special features, small package and reduced pin count interface makes it
suitable for cost sensitive platforms. MARIE provides a 36-bit Data bus SSTL-2 interface and is able to achieve 100
Msps in Turbo Mode. During normal search mode MARIE performs 50 Msps at 144-bit lookup. A special shifted
payload algorithm for the signature matching makes MARIE a perfect fit for IDS applications.
