Abstract: An associative memory that can be integrated with standard computer memory flexibly reduces its parallelism to match the memory bus speed thereby providing substantial increases in memory density possible by a multiplexing of sense amplifiers that otherwise dominate the memory structure. Apparent parallel operation is provided by an accumulator that reassembles the multiplex data. Higher memory density makes dual use of the associative memory as a content addressable memory and random-access memory possible.

Abstract: A memory module includes a memory device, a command/address buffering device, and a processing data buffer. The memory device includes a memory cell array, a first set of input/output terminals, each terminal configured to receive first command/address bits, and a second set of input/output terminals, each terminal configured to receive both data bits and second command/address bits. The command/address buffering device is configured to output the first command/address bits to the first set of input/output terminals. The processing data buffer is configured to output the data bits and second command/address bits to the second set of input/output terminals. The memory device is configured such that the first command/address bits, second command/address bits, and data bits are all used to access the memory cell array.
