Static NAND cell for ternary content addressable memory (TCAM)
Abstract:
A static, ternary content addressable memory (TCAM) includes a key cell and a mask cell coupled to intermediate match lines. The key cell is coupled to a first pull-down transistor and a first pull-up transistor. The mask cell is coupled to a second pull-down transistor and a second pull-up transistor. The first pull-down transistor and second pull-down transistor are connected in parallel and the first pull-up transistor and second pull-up transistor are connected in series. A match line output is also coupled to the first pull-down transistor and second pull-down transistor and further coupled to the first pull-up transistor and second pull-up transistor.
