Abstract:
A content addressable memory can include an array of memory cells having multiple memory elements, such as RRAM elements, to store data based on a plurality resistive states. A common switching device, such as a transistor, can electrically couple a plurality of the multiple memory elements with a matchline during read, write, erase, and search operations. In search operations, the memory cells can receive a search word and selectively discharge a voltage level on the matchline based on the data stored by the memory elements and the search word provided to the memory elements. The voltage level of the matchline can indicate whether the search word matched the data stored in the memory cells. The content addressable memory can potentially have an effective memory cell sizing under 0.5F2 depending on the number of layers of memory cells formed over the switching device.
