ABSTRACT:
An improved content addressable memory cell which employs a structure which utilizes a single transistor to discharge the hit line, and is driven by a self-blocking driver which glitchlessly changes state without the use of virtual nodes. Also disclosed is an alternative content addressable memory cell which can be written into in two distinct fashions, one of which permits the content of the cell to be changed without requiring the entire data word with which the cell is associated to be rewritten.
