Abstract
A tertiary CAM cell with three bits of storage, the three bits of storage are arranged to support three stable states which can be read from the CAM cell without requiring a charge restoration operation. The three stables states are those states where one of the three bits is at a first logical state while the remaining two bits are at a second logical state. The three stables states may be used to encode the three logical states used in a ternary CAM.
Claims7
A method for operating a tertiary content addressable memory (CAM) cell, comprising:
- setting a first of three binary storage elements to a first binary state to indicate a first tertiary state of said CAM cell,
- wherein in response to said first binary storage element being set to a first binary state, said second and third binary storage elements are each set to a second binary state.
