IMPROVEMENTS TO CONTENT ADDRESSABLE MEMORIES

摘要

A content addressable memory. The memory is arranged storing data words whose bits can take on an indifferent logical value besides two complementary logical values. The memory includes a matrix of memory cells in which a pair of cells is assigned to each bit that can take on a ternary configuration. Circuits are provided for memory matrix access control for providing access for performing comparisons during operation in the content addressable memory (CAM) mode or for writing/reading data by means of direct RAM mode addressing.
