    Abstract: Words of data are maintained in content-addressable memory cells arranged in rows. Two of the rows are timing reference rows, and the remainder of the rows are data rows that maintain the words of data. The data rows form individual matchlines. A first of the reference rows forms a precharge reference matchline, and a second of the reference rows forms an evaluation reference matchline. The timing for the individual matchlines to precharge is based on the time to precharge the precharge reference matchline, and timing for the individual matchlines to evaluate a search word is based on the time for the evaluation reference matchline to evaluate the search word.

    Abstract: The present disclosure relates to content addressable memories (CAM), and more particularly, to a searchable CAM structure having self-reference matchline precharge and local feedback control and method of use. The present disclosure includes a structure which includes: a sense line connected to a sensing device; a feedback line connected to the sense line at a tap point between a first end and a second end of the sense line; and a local precharge controller connected to the tap point by the feedback line to control precharging of the sense line according to a state of the feedback line.

    Abstract: The present disclosure relates to semiconductor structures and, more particularly, to sensing circuit for a memory and methods of use. The memory includes a self-referenced sense amp that is structured to calibrate its individual pre-charge based on a trip-point, with autonomous pre-charge activation circuitry that starts pre-charging a sense-line on each unique entry as soon as a sense has been performed or completed.

    Abstract: The present disclosure relates to memory structures and, more particularly, to double bandwidth algorithmic memory array structures and methods of use. The memory array includes: a plurality of memory banks each of which includes addressable storage units; a redundant array of independent disks (RAID) bank which stores parity bits corresponding to data written into any of the plurality of memory banks at a same address; and a plurality of XOR gates in which data written into any of the plurality of memory banks is cascaded therethrough to refresh the parity bits in the RAID bank.
