Ternary CAM

Ternary and Binary Content-Addressable Memory Compilers

eSilicon® embedded binary and ternary content addressable memories (BCAMs and TCAMs) have been provided to networking customers for over 15 years, helping these customers meet the demand for wire-speed packet processing, access control lists and other requirements of high-bandwidth delivery. eSilicon binary and ternary CAMs are available in geometries from 7nm to 180nm.

High-Performance, High-Density Embedded CAM Compilers for Network Applications

eSilicon offers a broad range of feature-rich, high-performance, high-density embedded BCAM and TCAM compilers. Our binary and ternary CAM compilers provide high-efficiency, cost-effective solutions for applications such as network search engines, cache for network processors, QoS services, classifications, Ethernet, ATM switches and other diverse networking applications.

User-Selectable Features

In addition to a full set of standard features, our TCAM and BCAM compilers provide a comprehensive set of user-selectable features that are chosen at compile time. Customers can choose just the features that they need for a specific application to optimize performance, power or area (PPA).

  • Priority encoder
  • Redundancy
  • Partial-pipelined search

eSilicon CAM designs are available in 7nm to 180nm geometries, optimized to meet challenging PPA requirements of IDM and leading foundry processes. We can supply ternary CAM instances or compilers to fit the number of instances required.

Features

  • Patented Duo architecture
  • Multiple architectures available in 7nm, 10nm, 14nm, 16nm, 28nm, 40nm, 65nm, 90nm, 130nm and 180nm
  • Flexible selection of width and depth
  • Up to 160Kb compiled
  • Up to 1K entries and up to 160 bits per word
  • Easily cascadable to increase search depth without degradation in performance
  • Single-cycle search, read and write operations
  • Smart Power Management and partial-pipelined search for reduced power
  • Fast cycle and access time: the 7nm TCAM delivers 1.8 GSPS worst case and up to 2.5 GSPS under typical conditions
  • Valid-bit, global and local valid-bit reset
  • Match-in and match-out flag for each entry
  • Flexible masking (bit/group/global)
  • Hand-crafted layout for high density and high performance
