Abstract:
A memory apparatus includes a content addressable memory, CAM, cell block including CAM cells and a random access memory (RAM), cell block including RAM cells. A geometric footprint of each of the CAM cells has a side bigger than a side of a geometric footprint of each of the RAM cells, where the sides of the CAM cells and the RAM cells are parallel to each other. The apparatus is configured to translate an input keyword at an input of the CAM cell block to an output word at an output of the RAM cell block when the keyword at the input of the CAM cell block is stored in the CAM cell block. The CAM cell block is split into a first part and a second part of the CAM cells.
