摘要

提出了一种具有耦合匹配线的三元动态内容可寻址存储单元。动态CAM单元仅包含4个n型晶体管。该单元能够存储和匹配三种状态，因此称为三元;这些状态是:零(0)，一(1)和不在乎(X)。电路仿真表明，我们的动态CAM单元以良好的速度执行所有基本操作(读，写和匹配)。为了在CAM阵列中使用所提出的单元，我们开发了一个截止方案来处理耦合。

A dynamic content addressable memory using a 4-transistor cell

A novel ternary dynamic content addressable memory cell with coupled match lines is presented here. The dynamic CAM cell contains only four n-type transistors. This cell is capable of storing and matching three states, hence the term ternary; these states are: zero (0), one (1) and don't care (X). Circuit simulations show that our dynamic CAM cell performs all the basic operations (read, write and match) at a good speed. In order to use the proposed cell in a CAM array, we developed a cut-off scheme to deal with coupling.
