Abstract

A high-density multiple-valued content-addressable memory (MVCAM) for applications such as database systems and pattern recognition is presented. The basic search operations executed in an MVCAM are both the threshold operations in each cell and logic-value conversion against multiple-valued input data. Various multiple-valued operations for data retrieval can be easily performed by programming logic-value conversion. Moreover, the cell circuit can be implemented using two transistors and one capacitor. The cell circuit is used not only to store multilevel charge but also to execute sum calculation by the capacitive coupling technique. As a result, the cell circuit is very simple and the chip area of the cell circuit can be reduced by 54% of that of the equivalent binary implementation.<>

使用逻辑值转换和阈值函数的多值内容可寻址存储器

提出了一种高密度多值内容可寻址存储器(MVCAM)，用于数据库系统和模式识别等应用。在MVCAM中执行的基本搜索操作既包括每个单元格中的阈值操作，也包括针对多值输入数据的逻辑值转换。通过编程逻辑值转换，可以很容易地实现各种数据检索的多值操作。此外，电池电路可以使用两个晶体管和一个电容器来实现。电池电路不仅可以存储多级电荷，还可以通过电容耦合技术进行和计算。因此，单元电路非常简单，单元电路的芯片面积可比等效二进制实现减少54%。
