CONTENT ADDRESSABLE MEMORY

OBJECTIVES

To familiarise with structure,features and working of CAM
Types of CAM and CAM cells.
Applications of CAM.
Working of CAM as search engines in Networking.
Future scopes of CAM.

INTRODUCTION

Memory devices store and retrieve data by addressing specific memory location.
The time required to find an item stored in memory an be reduced if the item is identified by its content rather than by its address.
Content-addressable memories (CAMs) are hardware search engines that are much faster than algorithmic app ....etc

INTRODUCTION
For many years, the field communication standard for process automation equipment has been a milliamp (mA) analog current signal. The milliamp current signal varies within a range of 4-20mA in proportion to the process variable being represented. In typical applications a signal of 4mA will correspond to the lower limit (0%) of the calibrated range and 20mA will correspond to the upper limit (100%) of the calibrated range. If the system is calibrated for 0-100 PSI, then an analog current signal of 1 ....etc

CONTENT ADDRESSABLE MEMORY
Content-addressable memory (CAM) is a special type of computer memory used in certain very high speed searching applications. It is also known as associative memory, associative storage, or associative array, although the last term is more often used for a programming data structure. (Hannum et al., 2004) Several custom computers, like the Goodyear STARAN, were built to implement CAM, and were referred to as associative computers.

Abstract Content distribution via network coding has received a lot of attention lately. However, direct application of network coding may be insecure. In particular, attackers can inject bogus data to corrupt the content distribution process so as to hinder the information dispersal or even deplete the network resource. Therefore, content verification is an important and practical issue when network coding is employed. When random linear network coding is used, it is infeasible for the source of the content to sign all the data, and hence, ....etc
